Yes, I dug out one I had made a few months ago and was going to take photographs.

Based on my experience doing all four bends in the same die may need something like 80 to 100 tons. I was doing a similar but smaller offset bend in 1-1/2 by 3/16 cold rolled bar and needed around 30 tons. The bottom line is that it would be possible to build something up to bend some samples if a big enough press is available. For large scale production you go to the experts and get a proper die made.
