Douglas TS fuel tank
« on: 27 Jun 2016 at 12:01 »

I have 2 x fuel tanks for a model TS, early 1920's, they have a few cracks/leaks on the welds which I would like to repair.
Does anyone know what the seems are welded with originally, it looks like lead????

I want to know what material this is before I hit it with the oxy.

The tanks are soft soldered. Careful with the oxy acetylene. I'd be using a large soldering iron.

Yes, don't go anywhere near it with the oxy/acetylene torch! A large copper bit (soldering iron) is what you need, and make sure you use the correct soft solder - tinman's solder is much better than plumber's solder. Having said this - you will probably have less hassle making a new tank than trying to seal up the old one - just use the old tank as a donor for fittings. The original tanks were made from soft soldered tinplate around .028" thick.

several clamps and some thin plywood strips.  as you solder it's going to want to pull apart, use clamps and wood strips to maintain seams as you solder.
