Insert your aluminum sheet into the brake beneath the removable clamp bar.

How to bend aluminium sheet at home. Make sure the bar is seated firmly inside the frame. Cut the section of metal out or otherwise prepare the metal to be bent by removing any burrs or sharp edges. Place the fracture line over the edge of a table and bend the overhang slightly downwards. 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.

When bending aluminum know that the smaller your inside bend radius the larger the chance that cracking will occur in the part. You will use the protractor to gauge the brake as you bend the metal little by little. Also know that for the best results and fewer cracks on the outside of the bend the bend line should go across or diagonal to the material grain when and where possible. Roll the wooden board firmly over to create a bend in the aluminum flashing.

The two m10 bolts in the top are to clamp the sheet between the backstop and the base. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius.

General advice on aluminum. The inside bend radius should be equal to the thickness of the material that you re forming. The backstops bolt holes have a slot cut in them to allow the backstop to be slid back to allow for the thickness of the material to be bend. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.

Then place the clamp bar back down on top of the aluminum crosswise.
