The Failed Press Bender

I first decided to make a press bender. It didn't work out too well. Either the radius of the bend was too tight, or the concept was not applicable to my standards, or a little of both.

I figured that this type of bender would make it easier to make mandrels for odd shaped tubes.

The Wheels. Skate bearings make it cheap.
