Got some time in the shop these days. Put some to good use and knocked up a break for my 20T hydraulic press.
I just have to paint and wait for the springs to come in.
Time will tell. Most I've seen use 2" angle or smaller. This increases the required hydraulic force. I used 3" angle which will decrease the pressure but may result in a curved bend rather than a 90 with straight legs. We'll see next week.
Probably a couple of years ago at least I posted pictures of a 20T press conversion from pump jack to air with a foot pedal control and my press brake and dies but I can't find it! I used 2in angle and depending what I'am bending can in lighter material get to about 1/2in return by stacking smaller angles inside the main die. The 3in angle itself would limit you to aprox a 2in return. For the nesting angles grind the o/s corner back a bit so they fit tight. Just have to get the right sizes so they set reasonably flush on top.
What you did there is pretty cool. When I saw the thread title which said press brake, I figured you meant one like you would find in a Fab shop or similar. I have a Verson press at work which got me to thinking, being this is a welding forum, it's interesting but they actually welded the name Verson into the Press, basically welding the logo into the cast Steel. It's a big Hulk of a machine, 84 in wide. I don't know how many tons but it will take a 3/4 inch square piece of solid aluminum 6 in long and smash it flat so it's a lot of pressure. At first glance you would think it was a bit crude to weld the machine company name on to the machine. But whoever did the welding, obviously with a stick welder, was a magnificent welder. I'll have to post a picture of it if I remember to do so tomorrow. The letters must be 5 or 6 in high.
What year did here to make the dies and saddles for them is pretty cool. I have a similar set up for making c channel out of 4 foot sections of 16 gauge stainless. Very similar to what you're doing here.

Reminds me of the shipyard welders out in Pearl Harbor, HI. They used to have to weld designation numbers/letters on a lot of the plates and machinery for some reason and did it all with stick. They had some impressive penmanship for sure with those stick welders. Their welds were actually better than my handwriting even when I try to make it nice
