Flip the sheet over and repeat.

Place the fracture line over the edge of a table and bend the overhang slightly downwards. 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.

The two pieces of sheet metal connected to each other by folding or bending tabs in the form of a buckle and a clamping slot.

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. The inside bend radius should be equal to the thickness of the material that you re forming.
