Pay particular attention to the rated capacity of a bending brake. It's too easy to convert one to a "break".
Many people make their own, especially for smaller widths but heavier steel or Aluminum stock. If you go to
www.hobartwelders.com and in the advanced forum search, search for METAL BRAKE and the user name DAN. That should give you links to the 14 different posts Dan made for the bender.
If you do a Google search for "dan bender site:hobartwelders.com" you will find more discussion and some other versions by various folks. I think this is the same bender, with the plans at post # 29. (Rocky D is still around, if you needed Autocad plans.)

There are plans for one type from a link here, though I have no experience with this particular one:
