I’m in the process of making some swaging equipment for the Corbin CSP-2 Mega Mite. I have machines a 1.5-12 die holder, similar to the external punch holder provided with the press. My plan is to drill it .875 through. Then I plan to counterbore the opening 1.25 diameter and using a retaining nut similar to an er collet nut to retain the die in the c-bore. I’d really like to draw jackets in swage mode, which has a 2.4” stroke. There is also an intermediate stroke length setting of 4”, but as we know you lose a little leverage as the stroke lengthens. I’m not getting any younger and would like to use the shorter stroke for drawing jackets. If I intend to do this, I’d like to pick your brains on drawing dies. I guess my main question would be if I can get away with my dies only being 1/2” long? I understand that the actually land of the sizing portion of the die is relatively short, but I’m curious about length of tapers/lead ins, etc. I plan on using the through hole in the retaining nut as a spot where my punch guide (which will slip over my punch and hold the cup) can seat into and square up my punch before pushing the cup through the die.
I haven’t drilled or counterbored my die holder yet. I’d like to hear what you guys think. Thanks!!
*On a side note, I know my dies don’t need to be 1.25 diameter, but I run a job at work several times a year and get 2” long pieces of O6 off fall. I probably have saved up 30 or so pcs lol.
