Building a sheet metal bending brake. It creates a t shape with the base angle. Weld the stud bolts on the bottom of the brake to make tightening and loosening them a one wrench job. The unit as shown is approximately 82 tip to tip has a working surface he. This will be used to make the bending plate as well as the hold down clamp.

The 2 plate was cut to 2 in length. I m sure some bright person out there will probably come up with a more elegant way to do this. In this video i show how to build a metal brake with a 72 inch working capacity. Use heavier metal stock for a stronger brake for bending heavier sheet metal or longer widths.

An angle is attached to the 2x4 and another angle is bolted on top of that to hold down the metal i ll bend. This will be used to form the smooth surface beneath the hold down clamp. The 2x4 is the base that will be clamped to a workbench when the brake is in use. The most important thing on a sheet metal brake is.

A third angle has handles and is hinged to the 2x4. All of the metal and wood bits were first cut to length. Mount this machine on pipe stands anchor to the floor or in the ground for long term use. Adjust and do a tack weld at side of pivot and the top corner of angle iron point 1.

The 1 5 angle was cut in half to make two 2 pieces. Twist a steel wire ø1 2mm around the pivot and place it at the gap on edge of bender.
