Sheet Metal Brake


Sheet Metal Brake

Here is the finished sheet metal brake, with the clamp leaf open. It opens about an inch, which allows for squeesing shut bend to form pockets, clips, joints, etc. The two levers on the top are to open the clamping leaf and to close and clamp (lock) it down on the bed leaf. The bending leaf is hanging down on the left-front of the brake. Becasue the some of the part of the brake are called leafs this is what is known as a leaf brake.

Here the clamp leaf is closed and clamped tight. Notice the bending leaf hanging down on the front. The working edge is the very top edge of the leaf. When a piece of sheet metal is held by the clamp leaf and the bending leaf is raised to a horizontal position the sheet metal is bend to 90 degrees.

The bending leaf has been raised to 90 degrees thus bending a piece of scrap sheet metal to 90 degrees.

The same peice if sheet metal after being removed. A perfect bend to 90 degrees.
