Take an Irwin vise, grind the teeth and tig weld these steps, put a stopper on the set screw and you have a flanged tool. I give 4 stars because everything is welded crooked and the seam on one side looks weird. I don't think their A-Team built them. As a welder, if my parts were delivered askew with a bad weld, they would be rejected. But in general it doesn't matter. They are designed for sheet metal forming and do the job well.
