Yes, you would wrap the sheet to form the overall tank shape, weld
in a baffle or three working from the open ends and then weld on
the ends to close things up.

'Kay. makes sense. Al I have to do now is learn to weld aluminum!

Or, you can drill holes in the outer skin where the baffle flanges
are located and then weld them from the outside. It's a lot easier
than trying to get a stinger in the tank.

Learn how to weld Aluminum? After a couple thousand in dedicated
equipment, and a hundred hours of practice, you'll certainly be
qualified. It's a little easier than turning crankshafts, I suppose.
If it was me, I'd spend my time doing fun things and leave the 20
minutes of welding to the pros.

It isn't all that bad, Rich. I use the same Smith torch and tanks for
aluminum as for steel. Use an aluminum flux and soft aluminum filler
rod. I would use a cheap spot welder to tack in the baffles. They
work great on aluminum.

Leave your outside seams as bent out flanges. Brush a little flux on
the flanges and melt them together with the torch. It really isn't
terribly tough. The flanges melt down and you don't even need filler
rod! See the Tinman videos on welding aluminum with a torch.

Kay, thanks John. I did try welding aluminum when i gt my bottles first
years ago, but gave up early on! Anyhow there was nothing for me to weld..
