Anyone have an easy way to bend metal into a U shape? I have access to several brakes. Making the first 90 degree bend is easy but how do you make the second 90 degree bend? Seems there's interference between the brake and the piece. I'm trying to bend .010 4130 strips (1.5 in. wide) into a U shape that has 4 in. verticals and a 1.5 in. base.
