The throttle cable routing I'd chosen didn't work. It put enough tension on the cable that it wouldn't return fully to idle properly. Helpfully I did realise that there was *one* thing in the right area I could just zip tie the cable to - one of the springs that holds the rear of the engine shroud on.

Image

That seems to have done the trick.

I noticed yesterday that she seemed a bit unwilling to initially rev up from idle from a sharp throttle input - that to me says "I want more fuel." Adding choke immediately made things better, which added further credence to my logic.

It's easy to tweak the base mixture setting on this carb as there are several (five?) notches which determine the needle height relative to the slide. It was set to the highest slot as supplied, which is the leanest option. I've moved it down by one notch (which effectively lifts the needle a bit), and that definitely seems to have made the throttle response snappier. I'm actually pondering going a slot further then reading the plugs after a few runs - two stroke engines being what they are given the choice I'd always choose leaning towards rich than lean. The odd fouled plug is far easier to fix than melted pistons!

Another horrible mid rev range buzz has been eliminated, which turned out to be the heat exchanger touching the air dam under the bumper. A very clearly not new rub mark there tells me that mine isn't the first bit of exhaust to do that. A little brute force was applied and has given a bit of extra clearance.

She seems to have settled down a bit now things have worn in a bit.

Still a decent number of things on the to do list, but we're getting there!

Fitting the new door window seals so they STOP FLUFFING RATTLING is probably next on the list. Preferably before the driver's door one erodes my sanity too much further.

Oooohkay...I have a lot of updates to catch up on. This is going to involve a fair bit of copy/pasting - so apologies if it's a little disjointed.

[] March 15th.

I did decide to lift the carb needle by another notch. This seems to have got us to the point where you can see a slight bit of smoke from the exhaust if you're hanging your head out the door and really looking for it. Based on my limited knowledge of two strokes, I think that's a pretty good indicator that we're where we want to be. I will also read the plugs after a hundred miles or so.

I *definitely* didn't launch the circlip off the needle when I took it off.

Image

Thankfully it didn't go all that far and I saw where it landed so no harm done.

Today the Trabant has gone away for a little holiday with a friend down by Dunstable who is going to address this bit of rust on the offside front...sill? Chassis rail? Chassill? I never know quite how you'd describe it on this car...base frames are weird.

Image

Image

They also spotted another bit by one of the front subframe mounts which will also be attended to while they're in there. We aren't worrying about the bit on the boot floor for now as there's not much point until the leak around the rear screen is sorted, it's miles away from a prescribed area right at the back corner, and isn't doing any harm.

This car is never going to be pretty, but my intention is to get it otherwise as well sorted as we can and knowing things like this have been properly attended to will be nice for peace of mind.

This trip was a little nail biting though in that it was the first time I'd taken the car out of town on a fast road for the first time since I'd changed the engine. Glad to report that aside from a slightly biblical smoke show after five minutes or so because we had clearly wet stacked the exhaust a bit with the local bumbling (and probably with how much oil I chucked into the new engine when I first started it) and it took a bit of time for that to burn off. The difference when buzzing down the A5 now though is like night and day, both in terms of how easily the car will maintain a ~55mph cruise and the noise levels while doing so. It's still by no means a relaxed way of covering distance on main roads, but it feels immeasurably less like it's about to spontaneously disintegrate than it used to.

While the Trabant is away I have been given this to bumble around in.

Image

Image

Image

Because it's traditional for anything which visits overnight, here's a dash-at-night photo.

Image

Occurred to me as I was setting out on the way home that despite having been messing around with classic cars since pretty much since I could walk, that I don't think I had ever actually even sat in an ADO16 until today.

Aside from an incredibly dim witted automatic gearbox it really is quite a charming little thing. It's a LONG time since I was in a car with hydrolastic suspension and I really had forgotten how well it works when it's set up properly. It's not going to beat something like a Citroen CX or DS, but she floats down the road just ironing out undulations and bumps in a way that absolutely nothing modern does.

I know quite a lot of people like to deride BMC products from this era, but it's roomy for the size of car it is, rides lovely, and with an A series up front was all tried and tested mechanical bits. I can see why they're popular in the classic scene and have quite a loyal following. Just a shame they didn't do a better job of corrosion protection of the subframes from the factory - though equally you could make similar accusations of just about any mass market car from the 60s in my experience. As was often the way with BMC though, it never really had the updates during its life span it probably should have had, and was hopelessly outdated by the time it was eventually retired.

It is kind of amusing to see the degree of badge engineering that went on with it though, and the lengths that they went to to try to make the dash in this Vanden Plas badged version look like it's a scaled down version of the one in a Rolls, even down to the black panel over to the right with most of the switchgear on it.

Quite looking forward to getting to know it a bit better over the next week or so. It's always fun getting to spend a bit of proper time with a car you'd never have gone out and bought yourself.

March 20th.

Nothing arrives on my driveway without some tinkering going on - or at the very least curious nosing around. This was of course going to be no different.

Image

The owner had made me aware that this car was leaking a bit of oil. Turns out that it was leaking rather a LOT of oil. The whole front of the car was covered, it was literally dripping off the front valance, and had gone from just over max to well below minimum on the hour or so it had taken me to drive home.

Image

The resulting drippage didn't just leave a puddle under the car, it left enough of a puddle that it ran clean out from under the car and off the side of the driveway. Not ideal!

The owner had had some issues with getting the oil filter housing to seal properly when they had changed the filter as the new O-ring was slightly too big. They were pretty sure they had mostly resolved this though, or so they thought. Turns out they had, the filter body to base join looked pretty dry - oil however had found the next weakest point and was basically peeing out between the filter housing and retaining bolt.

Image

The oil was then dripping off there, being finely atomised by the air stream from the adjacent cooling fan and literally spread over the whole front end of the car.

This also turned out to be due to O-ring issues - the one which sat between the body and the washer the bolt sits against and the filter body was clearly too small to be doing anything. Swapping that for a thicker one got that oil tight again.

Image

However I then spotted another substantial leak.

Image

It was weeping pretty freely from around the union for the feed to the oil pressure gauge. This had somehow both managed to almost completely unscrew itself from the reducer boss it was fitted to, AND said boss had mostly unscrewed itself from the block. Simply tightening these both up sorted it. OR SO THOUGHT...

After a run today the nearside of the engine bay was nice and dry. After the car had been left sitting for half an hour or so there was a tiny drip there which I think is due to a slight weep from the crank pulley seal. It's well within the "just keep an eye on it and make sure it doesn't get worse" range on something this old. However we did have quite a good puddle on the offside...which turned out to be that the oil pressure gauge union was loose again. Turns out if I'd taken it apart last time I would have spotted the cause. Originally the reducing boss was sealed against the block by a fibre washer. Said fibre washer had completely disintegrated, allowing both oil to leak out and the boss to back itself out. I didn't have any fibre washers in that sort of size in stock, but I did have copper ones - so have stuck one of those in there.

Image

Only been on a brief run so far, but it's looking dry so far. I will keep an eye on that just in case it backs off again but I reckon it will be fine.

Something which I had noticed is that the oil pressure in this car is astonishingly consistent.

Image

Though I did notice something which piqued my interest - that when you go from neutral into drive or reverse that the pressure dropped by about 25psi until the relevant solenoid actually engaged. Had they tapped off the engine oil feed to run the gearbox? Surely not...

It's stranger than that...no, they have run the *engine* lubrication off a relatively low pressure tap from the *gearbox* oil pump. This also explains why the oil filter housing leaked so much from what I would normally have expected to cause a pretty minor weep - that's because the filter is immediately upstream of the oil pump and before it gets to the pressure regulator which brings it down to ~100psi for the gearbox valve body (or 150psi if you select reverse). I hadn't noticed it at the time, but yes - the filter housing is way heavier than you'd normally expect, which makes sense now knowing that.

It's all in all a very strange setup, and very complicated for something intended for a mass market car like this. Surprises me as well that they went to the lengths of making it a four speed unit - a huge chunk of the market made do with three for another twenty years or so.

Stumbled across this in the glove box this afternoon.

Image

Which I recognised from a distant memory as being the lamp holder for the heater control illumination - something I had noticed wasn't working. Which it wouldn't if the lamp holder was in the glovebox.

The fitted lamp was actually physically too large to allow it to be installed, so I went and had a rummage through my stash and found a more suitable candidate.

Image

It is pretty dim, but the controls are so simple that all you really need is something to help you find where they are.

Image

Isn't that just so much more welcoming than any modern car?

Image

She is a bit tired here and there. The gearbox really does want the governor adjusted a bit, as it just bangs straight through the gears so you're in top by about 25mph irrespective of throttle position. The interior has about a thousand rattles and squeaks, and we're not convinced that the nearside front suspension displacer is long for this world, but it really is quite a charming little car.

The ADO16 is a car I'd never really given much thought to before, but it's definitely one I'd consider purely based on the strength of my time with this one.

Just hoping it stays oil tight now!

-- -- --

March 22nd.

I figured that it was about time I started actually making some progress on getting the Renault ready to move on. Having ignored it for a year hasn't miraculously made all the faults resolve themselves and gain an MOT, funnily enough. Why does that never work?

Step one was to stick the battery on to charge as unsurprisingly it was stone flat. It's entirely likely dead-dead given how long I reckon it's been flat, but we'll see. If I need to replace the battery it's not the end of the world.

Image

Oil and water levels were both still exactly where I left them. With the charger hooked up, the expected background things like interior lights and the clock sprang to life.

Image

I then made about an hour's work for myself. I couldn't remember exactly what worked and what didn't on the driver's door lock (it has the latch from the rear door on that side fitted as that kept jamming) - turns out the one thing which doesn't work is the key. The linkage however was quite happy to drop into such a place when I tried it and jammed the lock barrel - meaning I couldn't remove the key from the lock. Oops.

Image

No amount of wiggling the key, bashing the door or swearing at it worked. I had to strip down and remove the fluffing door card to reach in and push the offending bit of linkage out the way...which took 5 seconds.

Note to self: Don't do that again.

Next thing I planned to do was replace the bit of fuel line which had decomposed by the pump. However I bought that hose the best part of a year ago, and I'll be damned if I can find it. Have now ordered some more... that's a sure fire way to make it immediately reappear I'm sure. Once that's fitted the car will hopefully be back into a state where it can actually run and drive. My *hope* is that I can find someone to then take it on as it stands. However if that fails I'll jump through the necessary hoops of getting it an MOT first - though if you want it stupidly cheap as it stands (well, once it's running again anyway), I'm open to insulting offers at the moment.

I know it needs three fairly small bits of welding (one bit on a chassis outrigger where someone jacked the car in the wrong place god knows how long ago, and two bits on the inner wings where the seam sealant has failed and the seam has been attacked), a door latch so the rear driver's side door can be opened without having to body slam it from inside while someone holds the handle outside, and a pair of drop links fitted - though I can probably do that given the only tool needed is a pair of circlip pliers and I now have a pair that I *think* will fit.

Rusty bits, photos taken a couple of days ago.

Image

Image

This is an older photo, though given the car hasn't seen any salt, or indeed many miles at all since it was found I don't imagine it's much worse now.

Image

I'll be crawling around on that side when I fit the fuel line so will grab an updated photo then.

The other thing the car really needs is a head gasket. There's some oil contamination in the cooling system, though it's never pressurised it, and the oil has always stayed clean - so it's not failed catastrophically. The car has also never to my knowledge overheated.

It was finding this contamination that had me stop using the car as I didn't want to have it fail catastrophically and cause major damage - so hopefully should just be a case of remove head, clean everything up, have the head checked and cleaned, then reassemble.

Gasket, head bolts, camshaft seals, I think valve stem seals, timing belt etc has already been sourced (I just need to sift it out from this box full of Trabant and Rover bits!).

Image

The radiator also looks pretty tired though is leak free - so when I came across someone who actually had a new Nissens one in stock I grabbed that - that will also come with the car.

It's a really rare car now, and is a lovely thing to drive (or even just sit in!), but I just don't have the time or patience that it really deserves - especially as finding parts is now quite a headache as so many of the breakers overseas I used to use now refuse to ship to the UK. So time for someone else to have a bash at it before it decays any more just sitting on my drive. If nobody will take it on as a project as it stands I will get enough work done to get it mobile with a fresh MOT on it - but I'd really rather not have to invest the time and energy that I really don't have to spare for it to get that done if I can avoid it.

Additional report on VP oil tightness. Definitely improved.

Image

We do still have a bit of a drip for a couple of minutes after parking up on the offside, but orders of magnitude less than it was. I'd say based on that it seems like there's a fair bit of oil in the bell housing that we could be looking at a tired crank seal on this side as well. At least that's what I'd guess without digging any further. It's masses better than it was though, I really wasn't comfortable using the car as it was when it arrived out of concern for other road users.

Image

It seems to be a car which everyone just likes out and about - well, except for the impatient guy in the Tesla who spent ten miles so close to me on the way back from Buckingham that I couldn't even see the front of their car in my mirrors, and eventually overtook me via a gap which really wasn't big enough. He really wasn't amused when ten minutes later I ended up pulling up next to him at the Stoney Stratford A5 roundabout and waved cheerfully to him as I went past and he had to wait in the queued traffic waiting to go down the A508 which was backed up for some reason. It's the little things in life that you have to enjoy...

-- -- --

March 30th.

Well this isn't ideal.

Image

My camera has got hopelessly confused with the colour balance here (I did spend several minutes fighting with it before giving up). The offside headlight is actually a normal neutral 4000K-ish white. The nearside one however has turned a distinctly orangish-pink colour.

Good side:
Image

Bad side:
Image

Image

This is a pretty standard failure mode of any metal halide discharge lamp, automotive or otherwise. Basically as the lamp ages the halide salts are used up, until eventually the balance is thrown off - or blackening of the arc tube causes is to start overheating, which also throws things off and will usually manifest as a colour shift. It's pretty important that as soon as a halide lamp starts to show any change in characteristics that it's replaced then - don't just leave it until it stops working. For a very simple reason, it might explode! The halide salts are actually corrosive and over the life of the lamp do eat away at the envelope, so if operated until the very end they can (and in some cases do) go pop. Especially keeping in mind that the atmosphere in ones like this is somewhere in the region of 7 bar when operating, so there's quite a bit of pressure in that tiny little quartz capsule.

New ground for me as this is the first car I've ever owned with HID headlights (which in this case also swivel to look round corners), but something I figured I'd need to do battle with at some point, especially as the lights on this car are always on when the engine is running.

Surprisingly there is actually provision for replacement of the lamps here and it's not too bad to get to them. Though on the nearside the air cleaner/one of the ECUs is just close enough to the back of the headlight to be REALLY ANNOYING.

Image

The connector just pulls off the bottom, then twisting the big black tab you can see at about 10 o'clock anticlockwise releases the lamp from the housing.

Image

The silver boxes attached to the lamps contains the high voltage igniter - these require a pulse somewhere in the region of 20-30kV to provide the ability for hot restrike (as waiting several minutes to relight a lamp in an automotive application is a big no no). This arrangement with the igniter integrated into the lamp base vastly simplifies the wiring arrangements as the line between the ballast and lamp only has to deal with ~100V rather than the starting pulse. It's also the most likely component to fail, so having a new one fitted with each lamp isn't the worst idea.

A new pair of lamps are on the way and hopefully will be here tomorrow. At which point I'll find out precisely how much more annoying the proximity of the air cleaner housing is going to be in getting the new lamp into place.

-- -- --

March 31st.

Replacements arrived today. Shown here during the standard customs inspection.

Image

Failed inspection on account of being too boring and not edible. Better put them in the car then if they're not allowed in the house!

Shiny.

Image

Part number for those of you playing along at home.

Image

The driver's side is really easy. You can clearly see where the access cover is off below. This took roughly 30 seconds to install.

Image

Passenger side, not so much.

Image

Of course this one was the side which refused to just slot in wasn't it. Cue escalation.

Image

Eventually I figured out why it was refusing to seat. Around the perimeter there are a bunch of springy copper "fingers" which grip the metal housing of the igniter, presumably for RFI suppression. Two of these had been bent over so were getting in the way. Just to the right of 6 o'clock in the photo below.

Image

Given how ridiculously tight the locking ring was when I tried to remove the lamp from this side and scratches in that area on the lamp i removed I reckon these have been bent out of shape for a long time. With them bent back out of the way the lamp just slotted in and locked into place without needing to use unreasonable force. Which given the whole thing you're locking it to sits on a gimbal arrangement which can move in all directions is nice as you really don't want to break it as then it would be new headlight time.

Much better.

Image

Both lights are now the same colour. Definitely better than they were - definitely had a distinctly greenish tint before.

Image

Image

Be curious to take the car out after dark to see if they're noticeably brighter - kind of hard to tell just sitting in the driveway. Really do need to get the lenses properly polished up though as they no doubt aren't helping, and do let down the look of the car a bit. Job done for now though.

Now just to wait a couple of weeks for the skin on my right wrist to grow back!

-- -- --

April 2nd.

Had a brief it turned out totally unnecessary panic this afternoon when I came back out of a shop to find a large puddle of very rusty coolant under the VP.

This puzzled me on closer inspection. For one, it didn't feel excessively hot. Certainly not to the point I'd have expected it to barf large quantities of coolant. It's hard to put numbers on it or anything, but you kind of get a feel for what feels "too hot" and know when an engine smells too hot. This wasn't ringing any alarm bells. Secondly the coolant level actually seemed to be fine on investigation. The thing which really made me go "hmmmm..." though was that the coolant in the car was lovely and clean...not rusty Radweldy goop like was on the ground...Yeah, you guessed it. It seems I'd parked over a puddle left by the car which pulled out of the space right before I parked. I didn't notice because I walked away to the rear of the car.

I think one of the jobs for this weekend really needs to be to give the Rover a good clean. It's filthy from a combination of just winter grime and from dust kicked up while the landscaping was underway. I moved it this afternoon when getting some awkward furniture through the gate and could barely see out the thing reversing back onto the driveway.

I have fixed one fault on that car though (or at least I hope I have), which was tightening up the securing screw on the driver's wing mirror - so hopefully it will now stay where it's put rather than ending up pointing at the rear wheel after you hit the first bump. It's a tiny thing, but was a *really annoying* tiny thing when driving it. Especially as the driver's window really doesn't like opening or closing. That's probably going to be near the top of the list to investigate as again - it's really fluffing annoying and the sort of silly thing which leads to me just not wanting to drive the car. It actually works just fine but is really stiff so hopefully just needs cleaning up and the relevant parts lubricating.

Reckon with that and the front camber sorted properly so it tracks right I might actually be inclined to get some more miles covered and maybe actually start developing a bit of confidence in it.

Oh...and sorting at least the trip/odometer (they packed in last time I had it out) so in the absence of a working fuel gauge that I have *some* way to keep tabs on the fuel situation...That should also be near the top of the list I guess. Or try to sort the gauge - though that involves draining and pulling the tank, which quite simply put I really don't want to do, so yes I am indeed putting that off! On the plus side, I am pretty good at removing and installing the instrument cluster by now, so that bit shouldn't take me too long! I only had it out about 150 miles ago to attempt to sort the ammeter and replace several dead illumination lamps (one of which has already gone out again anyway).

Would you believe it, the Volvo is demanding yet more attention now!

Image

Bloomin' needy modern cars!

-- -- --

April 4th.

Finally got around to dealing with the small mountain of cardboard which we had ended up with in the conservatory. A lot of this originated from the engine and associated bits for the Trabant as there was a LOT of packaging involved in that. Plus we struggle with bin capacity for paper and cardboard at the best of times. That combined with a few kitchen appliances recently being bought meant it had just snowballed a bit.

Image

The big boxes there are all full of collapsed other boxes and packing materials as well.

Obviously it wasn't just cardboard I took with me, there were a bunch of old batteries, a couple of dead power supplies, some dead light bulbs and such as well. While at the recycling centre I found something downright unexpected in the lamp bin. Even better, there was nobody on that side of the yard, so it got liberated.

Image

Yes, that is a CO2 laser tube.

Image

I realise it's most likely dead, and I'm about 20kV short of having anything on hand to run it with anyway. Nevertheless it's still a fascinating bit of glassware to take a look at.

Image

Not something I've ever had a chance to look at in person before. I'll give it a clean at the weekend and get some better close up photos when I can.

-- -- --

April 9th.

Generally been pretty quiet over the last week or so here. Have found myself pretty much exclusively using the VP for local running around.

Couple of hundred miles have been done since the major oil leaks were sorted and the oil was last topped up. Still showing max on the stick (ignore it reading a bit high - that's mainly because of the slope of our drive).

Image

She definitely is still leaking a bit from the flywheel side of the engine, but it's reduced enough that it's not actually using an appreciable amount, just marking it's territory a bit when you park up. That's waaaay beyond any tinkering I'm getting involved in though. Changing a crank seal on that end of an A series is a non trivial task - especially on the auto as I'm pretty sure there's a special puller needed to remove the torque converter.

Ticked over 83K on the clock yesterday.

Image

I'm very much having to sit on my hands to not pull the speedometer out to lube up the trip/odometer gear train - that's 90% likely to be responsible for the speedometer essentially showing a +/- 20mph moving average at any moment. I haven't looked at how much of a pain it would be to get out to work on, as I know if I do that I'll end up doing it. Then I'll also end up trying to hunt down all the rattles and buzzes behind the dash, and that way lays madness.

Mostly though I've just been enjoying it.

Image

Image

Something I don't think I'd mentioned before as one of my favourite things about the car (aside from the suspension's ability to smooth out the horrendous roads around MK) is the view out over the wings and bonnet.

Image

That really doesn't get old.

It really is quite a cheerful little car and I definitely could see me with an ADO16 in the future one day. I really can see why they were so popular cars in their time. Feel kind of bad for having so completely overlooked them until now.

Today however the Volvo was back on duty as I had to make a run southwards to go and grab a little stash of parts. This involved entirely too much of the M25, but was otherwise uneventful and definitely worth it.

The gent in question is mainly into the Steyr-Puch side of things, but had ended up with a few Invacar bits and pieces, and having stumbled across my website reached out to see if I wanted to offer these bits a home.

Image

Big thanks to them if they're reading this as there's some quite useful stuff in there. Exhaust has some surface rust from storage but appears absolutely sound. The guy has said he'll keep an eye out for any more bits that might surface in the future.

The thing I'm most interested in is the carb. The one I have on TPA currently has quite a lot of wear in the throttle shaft, and even though it generally runs the engine well I know it's a problem waiting to happen at some point. This one seems to be in far better shape, so hopefully with a good service will be ready to go.

The coil is in far better shape than mine too which honestly looks like it was pulled off the bottom of the ocean. I'll be grabbing the support rod which sits between the intake manifold and air cleaner as well as I've currently got a home made one there.

-- -- --

April 16th.

Today the time came to drop the VP back off with its owner and collect the Trabant.

I've very much enjoyed my time with the VP and on the strength of that I could absolutely see me owning one in the future.

The reason the Trabant was away was to have this crispy bit of sill looked at.

Image

Image

As is always the case what you can see is only the tip of the iceberg, and this was no exception as we fully expected. Some photos were provided while the work was underway.

Image

Some grot was also spotted on the front cross member as well - including going behind the subframe mounting reinforcement plates. This definitely isn't ideal given that basically the whole front of the car is hanging off these two points.

Image

Let the chopping commence.

Image

Image

This also revealed a historic repair on the wheel tub - which most likely explains why this corner seemed so much worse than the rest of the car.

Some nice replacement panels were fabricated.

Image

Then was zapped in.

Image

Image

Attention was then moved to the cross member. This was done in two halves to deal with each subframe mounting point.

Image

Image

Image

Then same on the other side.

Image

Followed by some underbody sealant.

Image

Image

Just a shame that nobody besides me and the MOT tester will ever see it!

There are a few other areas which will want further attention in the future, but all well clear of prescribed areas and nothing that I'm imminently concerned about. However I knew this was seriously important structurally (especially given that basically the whole front of the car hangs off those two big mounting points to the cross member) so needed sorting sooner than later.

While I have very much enjoyed my time with the VP, I am very happy to have this little buzz box back.

Image

I do need to do a bit of clean up where the VP was parked prior to dealing with the oil leak issues...

Image

Finally did get the car transferred over to the historic tax class yesterday and logged as MOT exempt (despite that, it's still going in for a test next week) as I ran into issues last time I attempted to do that. The MOT exemption I'm not particularly worried about other than it making the logistics of getting it back a bit simpler, but I'll definitely take the £18 or whatever it is a month saving on road tax costs.

With around 100 miles covered since I last tweaked the carb, looking at the plugs I think I'm maybe a little too far on the rich side now.

Image

Which is good - I was aiming to go a bit too far that way then back off a notch on the slide setting in the carb to find what's probably the safest setting for the engine. With two strokes being what they are I'd always rather err on the side of rich than lean. A fouled plug is far easier to deal with than a melted piston.

Shortly after the engine swap was done I found this crack on the front exhaust section.

This was looked at while the car was being worked on, but was deemed too far gone to do anything with - pretty much as I expected given that the pipe was paper thin around that join. I did speak to a couple of places locally about having a system made up in stainless but they really weren't interested. Did consider just buying the middle section that's gone as the rest of the system does still have at least a bit of life left in it yet - but instead just pushed the button on a new 38mm system. Which should help get the most out of the better carb and overbore on the engine itself. I also don't like messing with exhaust systems at the best of times so don't want to be replacing one pipe now and having another bit go six months or a year down the line - hopefully this will be something that won't need to be touched for a good few years once it's all on there. Given we've got a fair few uprated parts on this car, it just seems a bit silly not to add the last bit to get the most out of everything. 38mm doesn't *sound* like a big exhaust bore - but the stock one is 35mm...This is a really small engine! Should make a noticeable difference at the top end I expect - apparently the baffling arrangement in the heat exchanger/expansion box up front is quite different to the stock one as well so flows considerably better.

Really happy to have the car back. This is always one of those areas where there's going to be a huge amount of placebo effect, but it seems to *feel* more solid and planted on the road. I guess this could have made a noticeable difference though given that we found that the rot had got into areas next to the subframe mounts off which the whole engine and front suspension setup is hanging - wouldn't take much movement there to be perceptible from the driver's seat. I'm pretty sure though it's entirely in my head and just knowing that there's not a big hole in structural areas any more is making my brain think the car feels more solid.

April 18th.

Had planned to go tweak the carb on the Trabant today (going to knock it back one notch), but as soon as I went to get the tools out the weather laughed at me.

Image

So I changed tack and went looking for a job I could do at least mostly inside. Of course it then never actually started raining properly. Ended up going for one job which functionally is minor but will be a huge quality of life improvement.

This was my chosen target.

Image

The front window seals are utterly knackered.

This resulted in two issues. One being that the glass could wobble around a bunch and it rattled incessantly. The second was that because it could wobble around so much that while you could open the window just fine while driving, if you tried to close it in motion the glass would do this and jam.

Image

I actually bought a full set of window seals only a week or so after I got the car (this includes windscreen, rear windscreen and boot lid as well) however I've been largely ignoring them.

Image

Have been putting this off as every time I've changed window seals before it's generally been an utter pig of a job.

Let's get into it.

Image

Spot the difference?

Image

Image

Image

Should have known the Trabant would be different.

Time taken: About 30 minutes. Tools required: One flat blade screwdriver (to help push the wiper strip at the bottom of the window into it's channel). Technically you don't even need to take door door card off.

I've only done the outside wiper so far as I want to attack the top of the inside of the door top with some cutting paste to try to remove some of the black grime from there and I know it will end up all over that, so doing it AFTER that cleaning makes more sense. The actual window seal just slides into the channel and can just be pushed from one side to the other.

I did take the door card off as I thought I'd need to (that again only needs one flat blade screwdriver and about 5 minutes work). That gave me a good opportunity to clean and lubricate the winder mech and hoover all the accumulated gunk out of the bottom of the door.

The difference when closing the door is ridiculously obvious, it really shuts with a solid thump now rather than rattling. It's a minor thing but not having the door continually rattling right in my ear will be a big quality of life improvement.

Also noticed that the passenger side wiper arm was closed to making a bid for freedom - the grub screw was loose, so that's been tightened up. Will get the passenger door window done tomorrow.

It will be strange driving the car without the doors rattling so much. The interior itself is actually surprisingly rattle free to be totally honest so it will make a lot of difference. Replacing the broken clip on the ashtray will get shot of the next most obvious one.

April 20th.

Carb tweaking was first on today's to do list.

Previously I had the needle set here, on the centre notch.

Image

I've now moved it up one to here.

Image

I'll take it for a run tomorrow afternoon then read the plugs again.

It is a good thing that this carb isn't any bigger!

Image

Image

Looks hard to get to but the fastening screw on the fitting boss is actually easily accessible from the right hand side, and the carb sits conveniently on top of the alternator while you remove the lid and mess with the innards. Takes all of about a minute.

Passenger door was attacked like the driver's one yesterday. You can see here how slack the glass was in the old seals.

Image

Just like yesterday everything was pulled apart.

Image

New seals in.

Image

The wiper seals at the base of the window on this side are in good shape so I left them alone.

I also took the opportunity to hoover all the detritus out of the bottom of the door.

Image

Which somewhat surprisingly included three usable trim clips.

Image

There has been a horrible smear of paint or something on the top of the inside of the driver's door since I got the car.

Image

This has defied all efforts to remove it with normal cleaning products, so today I hit it with some cutting paste to see if that would do anything - it finally did but took a fair bit of scrubbing.

Image

Have also replaced the torn wiper seal on that window now. This was far more of a fight than the outside one as there was a window in the way which was now fairly firmly held in place because everything else had been replaced.

Minor details seem to be the order of the day this weekend. Like the holes in the bumpers which originally held additional lights or something like that.

Image

Much tidier.

Image

Image

Same deal up front where I was missing two blanking plugs.

Image

Image

Oh, and finally wiped that oily handprint off the front panel and bonnet.

Image

Final quick job was dealing with a bright red cable tie in the engine bay of the Volvo which has been bugging me for at least the last six months.

Image

The solenoid which controls the vacuum supply to on the engine mounts (yes really) has a broken clip and was zip tied to its bracket. Fair enough but it was squint and had a red zip tie holding it on. Lined it up better and swapped for a black one so it doesn't stick out like such a sore thumb.

Image

Has only taken me six months to sort that...

-- -- --

April 22nd.

Hard to believe it's been a year again already, but once more I found myself here with the Trabant.

Image

Which shortly later resulted in this being issued.

Image

Which the car doesn't actually need - but I don't have a four post lift or a set of brake rollers at home. Plus I reckon the MOT represents excellent value in having a second pair of eyes look over the car. I'm only human and can and do miss things and make mistakes. Plus in the event anything did happen it's one less thing for insurers to quibble over. It will continue to be tested yearly. Fingers crossed I get to cover a few more miles between now and the next test...given the car was parked up for about ten months of the last test period after the engine went bang.

Had a look at the plugs when I got back from today's driving and this is what they have to say.

Image

One downside that was apparent with having knocked the mixture by a notch though was once again having to poke the cold start lever a couple of times before I got onto the main road and the engine started to do meaningful work and get some heat into it. I think this however is largely down the the supposedly smart choke as Mikuni call it trying to be too smart for it's own good. I'm sure the warmup profile they have works fine for a bike. The cylinder on a bike engine will heat up really pretty quick when you're stationary given there's virtually no airflow over it. This is a bit different though in that there's a great big (really quite powerful!) fan blasting cool air at the engine as soon as it's started - so I imagine it takes a good deal longer to get up to temperature than a similar capacity bike engine would. I'd really prefer to just have a cable attached to the choke control on the carb that I could set where I wanted it. Something I might have to look into at some point in the future. It's not a problem really rather just an annoyance.

I really do need to kick the idle speed up a touch as well as it is idling too slow currently - and being a two cylinder two stroke it makes it very well known that it's a bit too slow! Quite a contrast actually as as soon as you're off idle it really is a heck of a lot smoother than you'd expect. That is a moderate faff to adjust though as that screw is right on the back of the carb so is completely inaccessible with it attached to the intake boss...which given I imagine is going to require a few trips backwards and forwards dialling it in will get old in a hurry. Which is why I've been putting off dealing with that. I did see if I could cheat by tweaking the throttle cable adjustment (the idle speed adjustment is basically just a set screw which sets the resting position of the throttle slide), but that just makes the throttle hang 50% of the time...so no, I'm just going to have to do it properly, being lazy isn't an option. I did discover that I had at least 1/4" of slack in the throttle cable though, so it was worth messing with anyway as there's no way I'd have been able to get full throttle with it like that.

April 26th.

Well I do believe I've figured out where a recently developed rattle from the front end of the Trabant had come from.

https://youtu.be/wr8paaCq0N0

Generally bolts holding the exhaust system together shouldn't be merrily spinning around in place when everything is bolted together. That's what I get for reusing a couple of old fasteners with somewhat suspect looking threads. I've just nipped things up again for now as that will all be coming apart when the new exhaust arrives from Germany, so I'll replace the nuts and bolts then. The one nearest the camera in the video clip above is actually an utter pig to get to as it's near impossible to get a spanner or socket onto the underneath of that flange on the car as the exhaust itself, starter motor or crankcase are in the way pretty much every way you try to get to it. There's not much on the Trabant which is really annoying to get to, but that's definitely one example.

-- -- --

The beginnings of an engineering related Occasional Distraction (TM) are currently in progress. This is actually one that's kind of been at the back of my mind for a number of years but I've decided it's time to actually do something with as technology has progressed now to a point where I think it's worthwhile. Those of you who have put up with my ramblings for long enough will know that among the utterly useless in real life things that I enjoy is playing pinball. I was extremely happy to discover when I accompanied the family on a trip to Arcade Club up in Bury last year that they have a solid half of one of their floors dedicated to it. Though I really wish I'd taken the photo from the other end of this line where the more classic machines were rather than this modern Stern nonsense.

Image

I shouldn't really be too hard on Stern I guess - at least they're still actually making them. Plus there's nothing really *wrong* with them, they're just exceptionally average in my view and rarely hold my attention long. They've gone with lots of electronic fluff to try to draw people in rather than actually investing in designing a playfield that flows well and has any real replay value in my view.

I'm looking forward to visiting there again at some point, especially as they've apparently moved the machines since the last visit to a different area which is 16+ only so the perpetual stream of screaming ill behaved children who detracted somewhat from the experience last time should be greatly reduced.

There is a downside to enjoying this in the UK though, and that's that it never really was as popular here as it was in the US. This combined with pinball having enjoyed something of a resurgence in the last five or ten years has meant that machines in the UK are fairly thin on the ground, and are painfully expensive. For the vast majority of the tables I'd really want to dedicate a chunk of floor space in my house to you're looking very likely north of ten grand, and I quite simply ain't paying that much for something that is absolutely not useful in any way beyond providing entertainment.

Step forward the virtual pinball table. The idea of emulating tables on a computer is nothing new - It's a genre which has existed on computers pretty much since the dawn of computing (I'm pretty sure I've seen a video somewhere of one that somebody made running on a Xerox Alto). Obviously though there are big limitations to sitting at a desk looking at a screen and using a keyboard to control a recreation of a table, no matter how lovingly the graphics have been recreated and perfectly the physics are modelled - and some of the recreations that people have made are *incredibly* good.

You can take this several steps further though thanks to a few advances in technology in the last ten years or so - not least the wide availability of large 4K resolution widescreen displays. A 40" widescreen display conveniently is very similar to the usable playfield size of a "standard" table - and somewhere around 45" for a widebody table - even though that's a bit of an odd size that's not too commonly available, but if you're willing to accept a bit of fudging the numbers on perfect scaling a 43" one will work just fine and is a screen size which is orders of magnitude easier to find.

The basic idea is that you take the TV, flip it over onto its back, rotate through 90 degrees into a portrait orientation, and there's your playfield. That's immediately orders of magnitude more realistic feeling to look at than looking at a monitor on a desk. Though obviously you can't just have the TV floating in mid air or sliding around on its back on a desk, you need to have something to support it - a cabinet of some sort. Which then allows you to go several steps further and build other hardware into that cabinet which can go the extra mile to fool your brain (if done well, astonishingly convincingly) into thinking you're playing a real table. This is an area where the devil is in the detail. Firstly is that pinball tables are clunky, noisy mechanical things with powerful solenoids which operate most of the major functions - and you can only convey so much of that through a set of speakers. Well we've got a nice big box here, why don't we just build actual table flipper/kicker/pop bumper solenoids into it and trigger those at the appropriate moments in the simulation? That way near as makes no odds the same tactile feedback is transmitted through the body of the table to the player. This is made orders of magnitude easier by virtue of the fact that a few people who are *way* smarter than I am have already done the hard work in creating an IO controller which plugs into a USB port and allows you to drive all this lot from a computer. The same controller allows you to use real hardware for the flipper buttons, which again is something that always feels "off" when using a keyboard - or even microswitch based options. The illusion is further created by sticking another smaller screen up above the main one where the backglass and dot matrix display would be on a real table. Done well the overall effect is very convincing. No it's never going to be absolutely 100% as good as the real thing, but it's far closer than you'd think.

It should be an interesting project, albeit not a cheap one. Biggest obvious expensive bits are a computer that's man enough to run the whole show and the big playfield display. The table simulation take more horsepower than you might think (given that it's essentially a physics simulator) especially for more complex tables. We're also outputting the graphics in 4K resolution, and it NEEDS to be a solid 60+ frames per second without any stuttering or the whole illusion just falls apart.

The other big bit of expense actually is likely to be the cabinet itself. One of the best ways to make it feel like a real table to play is to use as much proper hardware as possible where it comes to things that you actually look directly at and touch. Also, it turns out that there's a reason that Williams/Bally basically didn't change their physical cabinet design after the early 90s and that Stern are essentially still using the same design today - and that's because it's a really good design that was arrived at after 50 odd years of refinement and evolution so there's absolutely no point in trying to reinvent the wheel. However before you've even looked at the structure itself that does mean that you've ended up with several hundred quid's worth of assorted "bits" of table. No one part is all that expensive really, but there sure are a lot of them. A company over in the US actually makes "flat pack" cabinets to the aforementioned Williams design which include pretty much everything you need to start building a system around - for $1500 (and shipping for a parcel that's the best part of 100kg from the US...Though if you're over there and wouldn't need to add probably another 50% on top for shipping/duty etc and if you're (like me) not at all competent where woodwork is concerned that's actually not a terrible deal. I ran some numbers a few days back and if I was to go out and buy all new hardware for that style of cabinet I ended up with a balance somewhere around £850. Yes that was both based on all new parts and I didn't do a huge amount of shopping around - so you could probably knock somewhere around a third off I reckon with a bit of work and patience. Still a fair old whack though, and still leaves me actually without a cabinet to attach anything to.

It's not hard to see why in the US when people really started building these things that stripping out old tables for it wasn't uncommon - especially given that they're a lot cheaper over there, especially older electromechanical tables. Though that has lost favour in recent years with the new reproduction cabinets becoming more popular. I've never liked the idea of pulling apart an existing table for something like this unless it was something that never had a snowball's chance in hell of ever getting restored. Such examples weren't really something that you really saw in the UK - those which were realistically beyond reasonable restoration usually had similarly knackered cabinets that I'd have been as well starting from square one anyway - though possibly could have been used to create templates I suppose - though as I've mentioned before, woodwork isn't my strong point. Which is why this had been sitting on the back burner for a while. Until a week or so back when I stumbled across a relatively tidy looking cabinet for sale on eBay at a not totally unreasonable price. It had already been completely gutted of the playfield, all the electronic boards etc, but the cabinet itself looked to be complete aside from the playfield glass itself. It's a bit sad to see it in that state, but the odds of stumbling across someone who has this exact table and has all the bits needed for it and is just looking for a cabinet, in the UK are slim to none. So it's pretty much ideal for my purposes. While still not cheap by any means - the vast, vast majority of things on that eight hundred quid shopping list I mentioned above are present and correct - plus the cabinet itself is there. So it's probably more than chopped the bottom line of that shopping list in half. I've dropped an offer to the seller - we'll see if they're willing to negotiate on the price at all. There are actually a couple of parts on there which I don't need which could probably be sold on - the backglass being one which actually looks in really nice shape.

The cabinet aside the two main components most important in terms of making this mess work will be the playfield display and the PC that will be built into it to run the show. In a somewhat counter-intuitive seeming approach these are actually likely to be among the last parts I buy. My reasoning here is simple - that for a given spec these are items which are only going to get cheaper - especially as I'm likely to be buying the parts there second hand as I don't need the newest and shiniest kit and these are things which are common consumer grade equipment for which there should be a good number of choices available on the used market. I *might* at a later date if this turns out to be something that gets a lot of use consider upgrading the main playfield display to an OLED panel, but that would be a long way down the road from where we currently are.

With a bit of luck this is something that parts will start trickling in for over the next few weeks and months and I can start figuring out exactly what I need to buy, what I need to make and what the headaches are likely to be. It should be an interesting project at the end of the day, and I'll be curious to see what the bottom line ends up being - I'm betting a whole lot less than any real table that's on my list, and gives me the option to mess about with pretty much anything that somebody has made a recreation of digitally, covering both traditional electromechanical tables of the 60s and 70s through to solid state tables of the 80s and 90s near enough to the present day. Should be an interesting project. Given this is something I've always enjoyed dating back as far as I can remember it's less likely than a lot of my projects to be something I run out of interest in halfway through.

April 27th.

Spot the difference?

Image

Yeah, have finally started doing something about the large chunks of paint that are missing.

Few examples.

Image

Image

Image

Image

I'm not interested in making an invisible job of it, I just want the car to look cared for and presentable from ten paces. So we're not going overboard. Bit of paint in the right places will make a big difference though and make the car look more presentable.

-- -- --

April 29th.

Example of how much difference a little paint can make.

Primarily the rear panel I'm pointing at here.

Image

Image

This sticker will have to go.

Image

I usually dislike stickers and similar things on my cars, but when they've been there this long I'm always a bit conflicted - this one though is shedding bits of silver foil every time I lean against the car putting stuff in the boot and is looking really shabby, so it'll have to go.

It's going to be an absolute pig to remove though as there's absolutely nothing structurally speaking left of it - except the actual adhesive of course!

-- -- --

April 30th.

Big old box was picked up from Parcel Force today. Which has been through the wars a bit en route.

Image

Though the innards were well protected and nothing had escaped.

Image

This is what was fished out after a solid ten minutes of de-packaging.

Image

It's astonishing how much pipe there seems to be in even a really basic car exhaust for a tiny car when it's off the car and inside the house.

It doesn't sound like a lot on paper, but you can definitely see it is bigger than the standard pipe when you compare them. Doesn't look ridiculous though. The 45mm one would look distinctly more conspicuous.

Image

Apparently there are differences to how the innards of the heat exchanger/expansion box are set up compared to the standard one. How much difference it makes in the real world remains to be seen.

It's actually only held on the car in four places, and they're all actually easy enough to get to. Only two require crawling around under the car, the ones on the silencer. I'll have a quick look at the state of those tomorrow so I know what sort of fun and games we're in for. Everything else has been off recently so shouldn't be too much of a headache.

-- -- --

April 30th (Part 2).

Went out to have a look at the exhaust on the Trabant. The intention was to just see what was going to be involved in removing it. Yeah, less than ten minutes later...

Image

Total of six fasteners - four 10mm bolts on the hangers and two bigger ones on the manifold clamp, and the jubilee clip for the heater outlet and the whole thing just drops off. The exhaust doesn't go up and over anything, and there's plenty of room under the car so it can just be pulled off intact.

Turns out the silencer was in pretty poor shape so I definitely made the right call to replace the lot.

Image

It's definitely perforated somewhere around the inlet side. Plus a black spot on the underside I originally thought was a splash of underbody sealant actually turned out to be a hole.

Image

I'm kind of curious to attack this with the grinder to see if the internal structure is any different to a "normal" one to optimise things for the two stroke application. It also rattles...so I'm kind of curious to see whether it's full of carbon crud - or the bits of metal which escaped from the original engine. I'll need to cut the main pipe down to take it to the recycling centre anyway as it's unwieldy with it being so long at the moment.

It's basically impossible to judge the condition of the front box because it's hidden away inside the outer shell - but it externally looks pretty rusty and given that it's most likely as old as the rest of the system I'd not want to trust it long term. Especially as there's very much a safety aspect here as a failure can result in combustion products being pumped into the cabin.

Less than an hour after I started we were done.

Image

That is the easiest exhaust swap I have done, ever. Okay, maybe the rear engined Skodas are possibly easier - assuming the fasteners hadn't rusted away to nothing and/or the manifold to downpipe studs decided not to snap anyway, though that always seemed to be a gamble.

I was planning to do this on a ramp, but it just seemed so simple I just got on with it.

It sounds way different. Will take it out for a proper test tomorrow, but a very quick run round the block shows it sounding far sharper, and it is definitely a bit louder - but not obnoxiously so given the car we're talking about here.

https://youtube.com/shorts/1pB2klY7dNo? ... 6NnjaJxQp0

Excuse the portrait video. I'll try to get a better one tomorrow and a proper test drive.

May 8th.

Today on "random things you can easily fit in the back of a big Volvo."

Image

Image

I did add a couple of straps on before driving to ensure that I didn't get decapitated by a pinball table if I braked too hard.

I do really appreciate the fact the design of the integrated dog guard. I don't have the back seats down very often, but the fact that I can just fold it up out the way without needing to mess about removing it every time is really nice. Oh, and it doesn't rattle which puts it say ahead of pretty much every after market one I've ever worked with.

Here's what will be making up the chassis for my virtual pinball table.

Image

Image

How long it is since this saw service is evidenced by the coin door.

Image

The fact that it says "NP" I'm guessing is "new pence" which puts it in the early 90s I think.

I absolutely wouldn't have been willing to pull apart a working machine for this sort of project - or even one which had any real chance at being restored. This however is one which has already been used as a parts donor to restore another table, which sits better with me. It's a bit scruffy, and isn't a cabinet that was used in many games, so the odds of finding someone who needs exactly this cabinet to get them going is pretty slim. Plus I'm not going to be massively hacking up the cabinet anyway, so if someone did want to restore it somewhere 30 years down the road I won't be doing anything to stop them.

I'll take a closer look at things tomorrow to confirm what we've got and to start taking some measurements so I can start making a shopping list.

-- -- --

May 9th.

Okay, let's take a closer look at this project.

Image

Which yes, technically is a very large, heavy wooden box.

Image

There however is a lot here that I needed. For a start, it's a very well built large and heavy wooden box. I am not a carpenter, so putting that together from scratch in a way that's both structurally sound and anything close to presentable looking is well beyond me.

All the bracketry to hold the playfield (which of course will be a display in our case) is already there and the geometry of that has been figured out to allow it to hinge up like a car bonnet for service access (there's even a prop in there to hold it up). Trying to engineer that all from scratch could have ended up eating up an unreasonable amount of time and cause a lot of frustration. I might need to drop the rear brackets down a touch depending on the depth of our display but that's easily done.

The metal trim along the sides and top of the front is important - as this is something that you physically lean on when at the machine. So it both needs to be sturdy, free of any sharp edges and of course being right has a substantial impact on if using the machine will feel right. That's all hardware I'd have had to either import from the US or try to find used over here - and the way it fits together is pretty precisely designed so I'd probably have driven myself insane trying to make it work with a homemade cabinet.

The plunger. Very important for many games where there's a skill shot on the ball launch. Hardware exists to allow this actual hardware to be used and the position reported to the simulation PC - so it will work just like the real thing. This is something you just can't replicate on a keyboard or anything like that. This one needs a good clean but will work just fine for our purposes. I'm pretty sure this is one of those cases where cleaned up old hardware is probably better than new hardware.

Buttons! Goes without saying that real table buttons and switches will have an impact on how realistic things feel. The actual switches are missing here but they're not expensive, the buttons themselves are still present.

Coin door. This is a surprisingly expensive bit of kit to buy a replica of (about $150 for a decent one, obviously plus shipping etc which would probably double that). This original one is HEAVY.

Image

While we won't be using coins, a button on the coin door (I'll be using what was originally the coin reject button to the left of the slots) to add credit is generally essential, likewise the position is present for the original start game button. A cabinet just needs the door to be there with the illuminated coin slots to look right in my mind.

The inside of the door also gives a good location to tuck away several additional controls that we're not likely to need often. For one, the three or four service buttons you need to access the operator settings on many tables (we are running the exact software used on the simulated tables, so all the system options are there to be meddled with). It's also a handy place to tuck away things like a master volume control, reset button for the simulation PC, random things like that.

Speaking of buttons - we will need to add a few more, though I'll generally be trying to keep them to a minimum. Some games use a "launch ball" button rather than a plunger, so one for that purpose will be added directly below the plunger. An exit button is needed to back out of individual games back to the menu system - the flippers, start and exit are basically all you need to navigate things, the front end software is really well designed. Extras will be a power button to start up the PC, which will be going exactly where the original would have been on the underside of the table behind the right front leg. There will be several power systems running in here, bunch of 240V supplies for the various displays, 12V, 24V and I think an oddball one at something like 38V for a couple of the bits of actual pinball hardware we'll be using as feedback devices. Is actually really easy to have this all turn on with the PC - just run a mains contactor with the coil fed from the 12V of the PC itself. This is good as it means we only need one power button rather than about five. I'll stick a double pole isolator switch on the back as well so I can turn it properly off without having to stand on my head finding the socket (most of them are in really odd places in this house!). The other button will be a "night mode" one which will disable all the noisy feedback devices if someone wants to use it without making a racket. It's not an issue for us here just now as the room it lives in is miles from any bedrooms, but I can't guarantee that will always be the case and it's something easy to implement. That will probably also go underneath the table in the same general area as the power button.

Last item of external hardware I can immediately think of would be the legs - these are another part that is fluffing expensive to buy. Which now I've seen how ridiculously heavily made they are I'm less surprised by, and all the correct hardware to attach them. Again, just one of those "why try to reinvent what they spent 50 years getting right" situations.

Displays are probably the single most important thing we need to consider here. Especially the playfield one as that's what we're going to be looking at. Something which is quite helpful here is that large scale 4K resolution PC monitors aimed at the gaming market have become pretty common in the last few years. Historically televisions had been the normal displays for the playfield, but they can be an absolute minefield in terms of image processing lag and suchlike, and questions have to be asked like "does it handle being depowered gracefully?" PC monitors are far better in these regards.

My usable space for the playfield display is 950mm by 520. It obviously can't come right to the front of the cabinet as the plunger takes up a bit of room there. This is a tradeoff pretty much everyone is happy to live with as it's worth it to retain the plunger.

Image

Image

A quick rummage around this afternoon turned up an ad for a secondhand 40" 4K gaming monitor for a whole £75. The dimensions of that without the stand are 904mm by 512. I couldn't really have asked for a better fit. The width (so height of the display) is the critical one as that's basically what constrains us, and the tendency for gaming monitors to have really thin bezels has helped us greatly here, as the largest TV I could find that would fit was 38", and we would be having to drop down to 1080p from 4K there.

The backbox internal space is approximately 630 by 360mm. Which is *astonishingly* close to a 16:9 aspect ratio, and I think a 24" monitor in there will do absolutely fine for our purposes - and I think I actually have one already in the loft which I can just chuck in there.

The little box which sits between the playfield and backbox is where the original score displays on this table lived - photo can be seen over here on the IPDB. Link. This is actually a pretty unusual setup, and we could go to great pains to recreate it...for a setup used on a total of two pinball tables (Eight Ball Deluxe Limited and Centaur II). Not worth it... I'm going to mount a 13" laptop panel (again...I have one in stock) in the centre to emulate any normal dot matrix display setups and put a pair of speakers to either side more akin to the arrangement used on later Williams/Bally tables. It's just going to be far more flexible and actually useful.

I'm picking up the main display monitor on Monday, at which point we'll be able to start actually piecing things together. Will probably be a fair while before it's actually playing tables as I'm currently short of a computer to run the show, but getting the main display actually mounted is probably one of the most important steps in making it work.

Will probably give it a good clean and properly put the thing together at the weekend so it looks more like a pinball table again rather than a coffin someone has upended in our back room

May 10th.

Ten minutes this afternoon and a moderate amount of swearing about how heavy this thing is had it looking more like a pinball machine again.

Image

It is insane how heavily built this thing is. Which makes sense for the intended application, but it's still quite something when you're used to working on domestic equipment!

The seller included a replacement for the missing lock on the coin door as well so that was installed.

Image

I mentioned there are usually operator controls on the back of the coin door before but never actually showed them - in the case of a relatively early solid state machine like this it's just a single momentary switch for the menu interaction and a volume control.

Image

I'll need to add another couple so will probably need a bigger bracket, but it will be in the same sort of location.

Plenty of room in the back box for a display. That hinged section will be likely removed as that's purely the backing for the original illumination. Though I *may* instead just move it back a bit and attach the display to that which might well be easier and more service friendly.

Image

Depending how we're looking for depth I may also put some of the mains distribution in there as it's both accessible and out of the way. We are going to end up with a LOT of clutter down here, so anything which can help tame the spaghetti is a good thing.

Image

Space for the middle display is usually a headache as it tends to end up in conflict with the main playfield display, but actually isn't too much of a problem for us - there's plenty of room in here for our score display screen.

Image

We'll just be using a 13" (ish) display in the middle rather than the original layout.

Image

A little cardboard aided design was employed to demonstrate the fit of two of our displays.

Image

Pretty much spot on for the playfield it looks like.

Image

Image

Let's me show how clever these brackets are too.

Image

Which I'm very glad to not have to engineer myself. For quick access to items under the playfield it lifts up like so, supported on the bonnet prop like support.

Image

Or for more in depth work it can slide forward and be tilted back slightly past vertical where the weight of the playfield itself then holds it securely propped against the backbox.

Image

The display will be a little deeper than the playfield so I may need to move the brackets down a touch, but I'll see how things sit first.

I think next step will be pulling out the remaining wiring (aside from the ground bonding) as I've no use for it and just give everything a good clean as it's all pretty filthy.

May 12th.

It's been a pretty busy week so haven't really had much chance to play around with car things. Trabant has mostly been out and about for local duties. Had an opportunity to get a photo where there's little on show to date things so grabbed it.

Image

Did have some slight excitement a couple of days ago when I heard the sound of something bouncing off the underside of the floor and saw in my rear view mirror a bolt bouncing off into the verge of the A5. Thankfully not into the front of someone else's car or windscreen, so that was a win.

I was 90% certain it was one of the exhaust downpipe flange bolts (I'd planned to change them with the exhaust but the ones I'd bought were too short). However the 10% uncertainty of whether it was something critical meant it was a bit nerve wracking while I got to somewhere I could safely stop. Sure enough my suspicion was proven to be correct.

Image

I need to get some further new ones that are the proper size (the internet was wrong *gasp*) as these are a bit too narrow but there are now spring washers hopefully stopping this from unbolting itself. Again.

Image

I'll double nut it as well when the proper bolts are in. You don't want to go too crazy tightening it up given you're clamping against a cast iron assembly - an expensive cast iron assembly that I really don't want to break one of the ears off of.

-- -- --

May 23rd.

Folks who follow this blog may recall that last year my trip to Birmingham for ConFuzzled in the Trabant ended abruptly at the side of the A45 just east of Coventry when it sounded like someone had thrown a bag full of marbles into the engine.

I still haven't actually torn the crankcase down to ascertain exactly where the bits of metal that got into the cylinders came from, but the consensus on inspection was that it was just utterly worn out. Since then a whole new power unit has been fitted (along with some other upgrades). So you'll be glad to know that this time round the trip was far less eventful and I made it in one piece.

Found the most ridiculously contrasting car I could in the car park to park next to.

Image

It definitely isn't a relaxed car for this sort of run, especially given you don't want to hold the engine at speed on a light throttle for long periods, so tend to adopt a bit of a "coast and burn" driving style. It works, but is definitely more stressful. I reckon once I get the gearbox sorted it will be better as it will probably make the car sound slightly less like it's really about to enter low earth orbit above 40mph. Actually kinda of harder to drive the car at 50 or so now as that now requires only about 3% throttle, rather than 40-50 before the new engine went in!

I can probably be a bit less hyper vigilant about things like that soon, but I'm still just about within the 1000km run in period, and holding the engine at continuous high steady speeds is something the instructions there specifically advise against. Given how much that lump of metal cost, I'm being careful. It's not really an issue around town because you're always stopping/starting there.

I haven't really gone looking for issues yet, but the only thing I'm immediately aware of is that the middle bolt on the front air dam has vibrated itself loose, so that's rattling. If that's all I have to contend with I'll take it!

The Invacar is definitely the easier of the two for longer runs like this. It's *really* surprising how happily that thrums along at 50-55 so long as it's not windy. The Trabant is definitely a lot more involved and a lot noisier! Also a lot more bouncy - though I'm withholding full judgment on the ride until I've properly serviced the springs as god only knows in what decade they were last cleaned and greased. It's not painfully jarring or anything (hello Mini) but is definitely a bit comically space-hopper esque at times.

June 7th.

Made a little progress on the pinball project today.

First was getting a few things ordered. Most importantly in the first instance being a pair of flipper button switches. The normal switches on this would actually have been on the play field itself I believe, whereas I need to fasten them to the side of the cabinet. Helpfully Gottlieb ones from the same sort of period used a flat bracket which will do just fine for my purposes. Hopefully putting Gottlieb parts in a Bally cabinet won't make it spontaneously explode...

The other bits on order (well not on order, I've actually asked a friend if they have any spares floating around first) are a compliment of eight solenoids which will be installed in the cabinet to provide audio and tactile feedback for when things fire rather than just relying on simulated audio through speakers (8x solenoids - two flippers, two kickers, three pop bumpers and the replay knocker). Additional to that will be a chime unit. This won't be needed on (most) solid state tables obviously, but will make things seem far more authentic when we're simulating electro mechanical tables.

Made a bit of progress on the cabinet as well. One step was pulling out the remains of the original wiring loom which I won't be using any of.

Image

A change I needed to make to the cabinet to allow for the use of the display panel essentially becoming the playfield was to drop that down so the surface of the screen is at *roughly* the same level as the playfield would originally have been. The sandwich of the display panel and panel it will sit on is exactly 90mm thick on the wide side, so I simply dropped down the original rails by that amount.

Image

The board containing the tilt devices had to move slightly as it would have wanted to occupy some of the same space. Was pretty easy to just shuffle it a little further back in the cabinet.

Image

With the display dropped down a bit it is starting to look a bit more like an actual machine again.

Image

In the space behind the playfield display there will be a trim piece, probably also fitted with some high intensity LED flashers to work in concert with when some high power flashers on the simulated tables would have fired - as that's obviously something you just can't get from an LCD display.

Image

There will also be a thin wood trim added around the edge so the asymmetric bezel of the display will be hidden from view once we're done.

I've taken some measurements in the back box. It looks like we *might* have room to install the PC in here.

Image

Aside from the historical symmetry as this is where the original MPU and driver boards would have lived it would just be convenient. There are already a bunch of nice mounting rails in there and it would be a nice way to help reduce clutter in the base of the cabinet. The big question is going to be if I have enough depth to play with - it'll be close, depending on how much depth I'm going to lose for the display that will also be there. It's not the end of the world, as I actually have a bunch of open space behind where the middle display will be, which is just a peculiarity of this slightly oddly shaped cabinet.

Image

Usually space in this area is at a huge premium in more conventional cabinets.

To be honest space is likely to be an issue once we get going with this - there's a lot of "stuff" to cram in there yet. Plus a LOT of wiring. Actually fitting it all in isn't so much a problem as fitting it all in in a way which maintains any semblance of serviceability and doesn't look like a complete rat's nest.

-- -- --

June 9th.

I really ought to know better by now. Seeing someone you know who swaps cars regularly with something you really, really like but figure it likely well out of your budget - and figure there's no harm in asking. Then find they were picturing a far cheaper price than you'd expected.

Well on the plus side, it has kicked me into actually starting to put together a few for sale ads for the P6, as that needs to go first (or at very least has a buyer) before I close the deal on anything else. Really needed to do that anyway as it's just sitting in the corner slowly turning green. It really needs a bit of money spent on it before it can properly start having miles covered and have the final few gremlins worked out, but I just don't feel invested enough in it to bring myself to doing that. It's a cracking car, especially for a design from the early 60s - but I've just not really taken to it. Really is funny how that goes sometimes with some cars, and highlights how much of a subjective thing what we like or don't like is.

-- -- --

June 11th.

Well a decision has been made and a deposit has been paid. Just seems too good a deal to pass up. The asking price was about a third of what I'd expected. Being probably my favourite colour for a car didn't help my restraint either.

P6 is very much up for sale. I reckon at the asking price of £4500 it's probably one of the cheapest decently solid P6s you're going to find.

Need to have a chat with a couple of folks to see what delivery is likely to cost as given it's a four plus hour drive away and I'm going to be pretty busy over the next week because we have family visiting I'm not exactly going to have much time available to go on epic collection missions. If I do go to collect it it would be a two day job with an overnight stay as getting myself there is the best part of 7 hours on public transport, and I know full well I don't have the stamina for that nonsense in one shot these days.

Will be the oldest car I've owned to date. Do folks want to try to guess what it is, or should I just tell you?

First of the more specialised pinball parts has turned up today.

Image

A pair of flipper switches.

Image

I don't actually have any real need for the big caps that are attached here as we won't be using these to directly switch a stinking great solenoid so back EMF isn't an issue. I'll probably remove them just to minimise clutter.

I need to make up a spacer to stand it up from then side of the cabinet, but they'll be positioned roughly like so.

Image

Hopefully putting Gottlieb parts into a Bally table won't make the universe divide by zero and spontaneously explode...

I really need to get the PC that's going to drive the thing sourced as I can at least get a basic proof of concept up and running then. That bit involves chucking a few hundred quid at it though, so might well wait till the P6 sells.

There you go - you're up to date. Congratulations if you didn't fall asleep and made it this far!

You have been busy! I like the Austin, drove a standard one for a while in the 90s, I loved it such a comfy thing...I used to own a vdp that was written off 15k miles from new... my brother took it on when I moved..
What would the laser tubes be used for, Cutting international spies up ?
I quite like the table thing you've making, is it a one off or do you have plans to sell them? Either way it's a good idea!

Laser tube will be from one of these things - Amazon Link. Or something similar, most likely a little larger than that one but same basic idea. CO2 lasers are actually used for medical purposes as well, but I'd be expecting the tubes in that kit to be from a traceable manufacturer rather than some random nameless Chinese drop shipper.

The pinball cabinet will be a one off. There are several companies that sell them now, but for a full scale machine you're talking the best part of ten grand, and even those have drawbacks. Namely that you're usually tied into a particular commercial source for the tables. Here however I get to decide what software goes on there and essentially gives me a library of literally thousands of tables which have been recreated by enthusiasts, in many cases in truly stunning detail and accuracy. It also means that as time and technology moves on I can simply upgrade it to keep it relevant, rather than being stuck with a proprietary piece of hardware with a limited lifespan.

Would be a very expensive thing to be trying to put together to make any money on without an astronomical price though - just the cabinet itself is north of $1500 plus shipping from a supplier in the US. Using old existing cabinets is generally somewhat frowned on given that it usually means you've pulled apart an existing table to make a virtual one. In my case I found someone who had already used this table as a parts donor to restore another one, and given it's a cabinet that was only used on a couple of games, the odds of finding someone who wanted exactly this in the UK to do a restoration were slim to none existent. It was an ideal candidate. Plus I'll be making the bare minimum of mods to the cabinet itself that I can really get away with, so if in 20 years time someone does want to undo my work and restore it into a minty fresh Eight Ball Deluxe LE, no reason they can't. The only places there will be any large cuts happening will be a couple of circular holes in the bottom and back for fans, and those are well out of view places where it wouldn't be hard to repair in a way that nobody would ever notice. Will be a few small holes required for some additional buttons - but all small enough that a bit of wood filler and paint and you'd never know they'd been there. I figure if I wasn't using it for this it would either end up buried at the back of a garage for the next 50 years or wind up at the tip. This to me seems a better use.

I can't see anything wrong with the modified table, it's going to be used instead of being left to rot or going in the skip.. I will follow this with interest :thumbs:
The chap who did the welding has done a tidy job, it's nice to see it on the road again...
When does the latest addition arrive? It took me a couple of days to read your updates.. every time I sat down for a quiet read I'd be interrupted by the kids/wife/dog/cats etc.. so I may have missed a bit :D

I think the big issue for a lot of people with using actual cabinets to make virtual tables is that back around 2010 or so it was becoming not uncommon for people to end up gutting perfectly good, working tables to make virtual cabinets. Which doesn't sit well with me for something that's survived this many years, especially as someone who has a hobby of restoring old technology. This example however didn't in my view really have a snowball's chance in hell of getting restored, and was most likely to end up either in the tip or chopped up and end up with some bits screwed onto the wall of someone's home arcade or something like that. Even that's probably a stretch as the paint isn't in great shape. This really is the best shot it has of being useful, so I'm really glad that I managed to find it as it also makes my life a heck of a lot easier. Simply because I Am Not A Carpenter and figuring out what to use as a cabinet was going to be by far the biggest challenge in the project - so finding that already made and at a price that didn't entirely break the bank was a definite bonus.

New car should be getting delivered on either Thursday or Friday - it's a fair distance away so I'm not entirely sure which of those days it will actually arrive here. The distance is the only reason I went for that option as otherwise I'd have been looking at a 7+ hour trek on public transport, a hotel stay at that end plus a 4-5 hour drive home the following day. It was going to end up far more expensive than delivery and given my stamina issues these days would probably wipe me out for the best part of a week - oh, and I have family staying next week so I'd not be able to escape for the collection mission anyway!

Only by a little bit, but will be the oldest car I've had on fleet to date. Probably not an acquisition which will really surprise folks who have been reading here a while though.

So what was it that was delivered to me yesterday evening?

As I said, if you've been reading this for a couple of years this will likely not surprise you in the slightest.

Image

Image

Image

A couple of years ago I had another one of these which I really liked. Unfortunately though it really was just too rough to make sense as a long term proposition - about the only things on the car which weren't just worn out were the gearbox and back axle. Despite that though it still drove lovely and was a car which left a big impression on me. I'd always figured that one day I would have another one, ideally in a bit better shape.

This was very much an eye opener for me into what massively underrated cars these are.

Image

This one popped up on another forum a month or so back, and I spent a lot of time sitting on my hands before finally deciding to ask the owner if they were interested in selling it, and if so what they'd be looking for - figuring it was likely to be out of my league. Instead they suggested a lot lower price than I'd expected. The result of that was pretty inevitable really.

While this isn't anywhere near a concourse car it seems a lot more of a sound proposition than the last one.

Image

Image

Image

Haven't really had a chance to look at things too closely yet as we've got guests staying with us at the moment (and it's a million degrees outside). Looking forward to getting a chance to take a proper look at it!
