As usual, I have to find a way to save money on my '32 build. I had intended to use the original seat frame and springs, but the springs are pretty bad. The set of springs will run $400+ and new frame $650+. I think I can fab a frame from 7/8" round tubing (smallest dies I have), but need some help with the "how to's" such as mounting zig zag springs and figuring their length before and after mounting. Also need help with what to use to hinge and lock/unlock back of seat. Any suggestions will be appreciated. I really need to make this work. Thanks
