The aluminium I bent was 0.038in or about 1mm thick and the longest bend was 310mm, just over 12 inches.

In bending, there are two big problems – holding the metal against the bending nose, and stopping the metal from sliding out of the press. Also the hinges have to be very strong.
As I haven’t any welding gear I wanted a hinge I could use with wooden boards. They are old melamine faced shelf panels. I connected them with strips of seatbelt webbing fixed with hot-melt glue. The belting is in tension when it holds the top board against the workpiece. These pictures show how it works.
