I have one of these benders and personally, it ain't worth a cup full of cold pi$$. I messed with this piece of junk for a couple weeks till I finally wised up. I made a set of custom dies, a tubing support and proceded to pull my liver loose trying to use this thing. I am 245 fairly stout for an old man and could not bend 1 inch except lite ga. aluminum, worthless for frame work. Used a come-a-long on it and bent the heavy wall tube handle. Want one? drive to Indiana and I'll give you this thing.
