As the song goes; "A long long time ago........", I built a sheet metal brake. It works fine, but I can't bend four corners of a box. I want to start over or modify, changing to high clearance and removable fingers or some other way i can fold a box with 10" high sides from 16 gauge aluminum. I now bend two sides, and add two ends. While I love welding time, distortion is a concern.
Has anybody got a good design?
