How to bend sheet metal without a brake.

Mount the brake on saw horse or your workbench with a few inches hanging over to allow the brake and slide a piece of sheet metal between the 7 and 14 plate snug the bolts down to clamp it and pull the pipe handle towards you to bend the metal.
I used a file to create a flat spot in the hold down angle used a metal punch to create a start for the drill bit and drilled a hole for the carriage bolts.
Simple sheet metal bender using a hand roller clamps and plywood.
However as i had designed the brake the bending point was 1 8 above the pivot point of the hinge see left side of drawing.
At this point it became apparent that i had made a mistake in the original design of the brake.
I then put the hold down in place and marked the hole for the carriage bolts on the hinges.
Ideally the pivot point of the brake will lie perfectly inline with the bend line of the metal being bent.
