Welded Box and Pan Brake
I’ve always wanted a box brake. This was a cheaper and more fun solution than buying one. It’s a standard design, 18″ wide and can bend up to 20 ga steel. The finger clamp cam is my favorite part.
Thanks for watching.

Excelente doblador a amigo..saludos desde chile
Nicely done! I've got 11 years in "hand" fabrication with sheet metal and this is the only build I've seen where the EDGE of the bending leaf is in contact with the metal and does the bending just like a "real one". The finger brake I used was 48" wide and could handle 14g material.
very nice design. I am thinking of making one like it.
Now that is a project I would love to take on with my everlast welder.
Novel approach on the hinges. You didn't cut anything out to weld them to the bend line, but added material thickness to the purchased hinges to get rotation about center. I have wondered if purchased hinges had too much slop. Everyone else cuts the angles and uses tubes with pins for centering hinges. The only thing lacking is the finger adjustment for different thickness of material to be bent. Something like the chain tightener on a motorcycle rear wheel would make this complete. Your "gantry" doesn't appear to flex when you make a bend. I'd like to go to 16 ga. steel and 24" with. This concept should work for that provided I make it stiff enough. I'd like to see more detail on the relationship of pieces and less sparking the welder and smoking holes with the drill press. Thanks for the ideas. One of your replies below suggests that you can't bend deep enough boxes. Yours appears to be able to bend deeper boxes than any other that I have seen. I would like to have 4" depth. I didn't see the "bender" sticker. I'll look again, and also see if I can figure out what Matthew Warfield was talking about with the "edge of the bending leaf is in contact with the metal and does the bending just like a 'real' one."
