Re: Tinsmith's in frame gas tank for cantilever Schwinn.
Pictured below is the tank I made sitting in the 53 Schwinn frame. I placed the filler on the opposite side from the other tanks and was able to punch holes for the site gauge fittings in a more optimum position since it was done before assembling the sides to the top piece. This allowed a longer run between the hose barbs and is better than what we did on the copper tank. I'm not sure yet if I like the looks of the site gauge, but I know I will like being able to see at a glance the level of fuel in the tank.
Thanks for following along on this thread and good luck with your endeavors.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
