Does anyone know of an affordable tube bender that can handle thin walled steel tubing for bicycle frame building? As an example, I would like to build a recumbant that has a 1 inch tube with a wall thickness of 0.049 inches that needs to be bent 90 degrees. This tube is for the chain stays.
There's all kinds of crazy to simple benders, go Googling for a while and you'll find ten different ways to do it on the cheap.
