    To do 3' of 3/16 i would say 30T-50T depending on the width of your bottom die. At least 8 times the thickness of metal so 3/16x8 =about 1 1/2" wide die. If your brackets are only a foot wide you will be ok...Bob

      Make your bottom die wider than needed & drop in smaller pcs. of angle if you need a smaller bottom die.

        That is what I was thinking of doing. That way I have an ideal gap in my die for each type of metal I am bending.

          I just measured the one I built years ago. The bottom die is 1.5". It will bend a 16" long pc. of 3/16" & an 8" pc. of 1/4". This is on a 20 ton press. I have a pc. of 1x1x.25" angle to drop in for lighter stuff. I wish I made the bottom die opening bigger.

            I mocked my press up today on the computer. Now I have a good list of material to head down to the steel supply and get what I need.

            What do you think the best way to put 44 holes through 3/8" metal is? I was thinking about making a circle jig for my plasma and then lining it up and clamping it down to put all the holes in at one time. 3/8" is a little bit thick for piercing with my cutmaster 42, but I think I'll come up with something.

              Drill a 1/4" hole first...Bob

                Well thanks for all the help guys! I've got a good design put together. I need to get some other projects done first. I picked up a 2.5' by 8' piece of 1/2" plate and some 2"x2" square tube today. Going to build a welding table first. Then a cart for my tig/stick setup and plasma and various c-clamps, grinders, etc. Then a tube bender from stacked 1/4" plate plasma cut out to shape. That should keep me busy for a day or two. I have been wishing for a welding table for a while now. I have a compact space so I think that size will work great. I'll post up again in this thread when I get my press built. Hopefully it will be faster than bob!

                    This guy has designed a near perfect press. I'm planning one similar, but better...

                      I was just fabbing some 3/8 brackets for work and my cutmaster 42 was struggling to pierce it. The small hole would help tons.
