I just got a HF 20-Ton Press this weekend. Besides using it for it's intended purpose, I would like to bend some iron with it. So I proceeded to come up with a plan. My box of parts for the press came with one extra cast plate, so I took all three and set them with the big Vee up. Next I needed something that would bend the metal better than the round bar stock coming down. I found that 1/4" wall 2X2 square fit over it perfectly. I was going to cut this into a vee and weld a piece of angle to it. But, TD&H (Brian) posted a suggestion to use 1/2" thick material on end here. I remembered I had some 5/8" thick stock, so I proceeded to make the vee on the edge of it. Cut a 3" long piece of the 2X2 square stock and welded that together. I needed a way to hold this die up onto the round stock, so I drilled a 5/16" hole through and welded a nut on for the holding bolt. Tried it out on the 1/2" bar stock I want to bend (5th pic below) and it is a go! A little heat on the bar stock will help as I need to bend them a bit more than they are now.
Here's some pics!
