I made a small bending jig this weekend to use on my hydraulic press. I needed to put some 90 degree bends in some bar stock. I would have bent the stock in my vise caveman-style with a hammer, but the throat on my vise was too short. Just the excuse I needed to make this jig. I've tested it on 1/8" bar stock, but it appears to be able to bend a bit thicker.
