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

As a side note, you will also notice in the previous post that the piece Dan is bending has at it's end a flange bent into a shape coming back on itself. Take a look and you'll see what I'm talking about. This flange is there so that the bottom piece has something to fit into, avoiding an impossible butt joint. Again there is a specialized tool for this in a tinsmith's shop, something you and I will never have. A couple photos show it in use. Dan can clarify what it's called; I forget. He said that without such a tool the bend can be improvised with something to act as a form for the tin to be bent around. He demonstrated for me with a screwdriver clamped into a vise, tapping the tin around the screwdriver below the tip. It wouldn't have to be a screwdriver... you get the idea. More will follow through the day as I have time to continue this thread.

Someday when I grow up I will probably lose interest in toys with wheels, but until then...
