The setback(setting that controls the radius of the bend) is flawed. Instead of it being adjustable from the shear line to around 1/8" behind the shear line, it's instead adjustable from about 1/16 PAST the shearline to 1/16" behind it. This severely limits the range of materials that it can bend. Unfortunately I already tossed the crate. I give it an extra star because it is functional in the limited range that the defective design allows. Was able to get crisp bends in 20ga copper sheet.
