Make sure the bar is seated firmly inside the frame. The sheet metal i am forming is 20 gauge. How to bend sheet metal without a brake. 3 16th thickness steel is the max thickness most scrolling machines accept.

Bending is one of the most common sheet metal fabrication operations. This is done through the application of force on a workpiece. Punch and die are manufactured with certain geometries in order to perform specific bends. Lift the clamp bar away from the rear of the brake frame and slide the sheet in perpendicularly to the direction you want to bend it.

The force must exceed the material s yield strength to achieve a plastic deformation. I like scroll work but a lot of it looks very skinny and weak. I can not make thin u channels. Then place the clamp bar back down on top of the aluminum crosswise.

This would be ideal for a press brake but i do not want to invest a ton of money in a heavy duty one. The easiest channel bending process is flanges out flanges in channel bending can be difficult if the flanges are relatively tall. Also as aluminum comes from the mill it develops a coating aluminum oxide as it cools. π 180 x b x ir k x mt bend allowance ba where b is the angle complementary to your desired bend angle 1 to 180 degrees mt is the thickness of the material ir is the inside radius and k is the k factor.
