Ash framing

#1 Post by valman »

Hi, New member, so just feeling my way here.
I'm restoring a 1938 Alvis 12/70 box saloon. Engine overhauled & running, chassis painted and true. Muliners Steel Body is off as I have lots of wood work repaire to make - my first time for wood frame repairs ! Wood frame is still bolted to chassis to keep it as true as possible during the work. Extra temporary bracing will be added when required. At least one of the A posts need replacing in large part & sunroof drainage & rear wheel arches & all the plywood (woodworm).
Now for my question. I have found a cotton type tape and sometimes a cotton cloth has been used originally between all ash parts and metal parts - even between the ash & the steel brackets which are just bolted / screwed to the ash frame itself (not the chassis). I find cotton cloth even between ash to ash parts. I find cotton cloth between ash and the original plywood, where it was used. I can understand cloth between the ash frame and where the metal body touches, to prevent squeaks, but what might the reason have been for its use everywhere else ? I need to decide what to do as I replace wood sections. Can't find anything in my books / internet on this. Suggestions / experience of materials used welcome.
Regards Mike V

Hello

Is the cotton just cotton or is it loaded with a wax or gummy/putty substance? This could be a caulking like the stuff used in traditional boat building. It is used in something like the way we use seam/bonding sealers today. It fill gaps and give a good bed onto which bits can be seated.

There is a good choice of newer materials you might consider when rebuilding the woodwork. Webbings, mastics and sealers. Along with glues etc. That sounds like a fun job.

Good luck with it.

Hi Mike,
I too am restoring an Alvis (TA-14), the work has stalled now as I got a new unpaid job as a parent! The woodwork was already done when I got it, but I don't see any sign of the material you speak of. I haven't noticed anything other than ash & aluminium to be honest.

I'd love to see some photos of your work if you have them!

Good luck with the restoration!

Paul.
