Default Re: Tinsmith's in frame gas tank for cantilever Schwinn.

my last tank i made a "buck" for the sides out of wood. i cut the copper sides about a half-inch larger, then centered the buck and pounded over the edges with a rubber mallet.

with copper, it's really easy to get edges on small curves, 'cause the copper's so soft.

corners ain't so easy. i had to snip those and solder them together.

the tin looks cool, and once you start with a copper tank, you'll be amazed at how easy it is to solder. much easier than sheet metal, in my experience.
