so I made a bending die for my press to see if I could bend some 1/4 in cold rolled steel. well it will bend it easy but if I bend it too far it just breakes it. Im sure if I heated it up it would bend with a nice tite radius pretty well. I think the corners at the 45 deg. of my "V" block does not help being rather sharp. if the corners were a smooth radius transition into the "V" the steel would not bite the corners and would want to slide into the "V" easier. I will have to buy a cheap V block and grind the corners. this is a good precision block I dont want to ruin. you can see the gough the block put on the steel in one of the pics. I think it will work great for thinner stuff, and if I need to bend 1/4 in I will heat it up first.
