Bend it
This design-and-make plan will enable you to make a small pan sheet metal folder that folds mild sheet metal from 18 to 26 gauge. With it, you’ll be able to fold “U” or “Z” sections or a lip on a sheet of metal. The way we’ve constructed the metal folder will also allow you to bend metal to more than 90 degrees—try that with two pieces of angle iron mounted in the vice.
