Although it's not well known, some in the swaging forum have drilled the linkages and reset the pivot pin closer to the ram for more leverage. This will effectively give you more leverage at the cost of less ram stroke.
Yer gonna do what?
Before anyone says "you shouldn't do that" let me just say that a few have and it seems to work quite well for easing tough sizing operations like swaging.
1st things 1st, getting it apart. If anyone has disassembled one I'm all ears. I have the ram top removed, see pic, and the link pins are exposed fron the inside. I'll try to push them in or out this evening. I'm hoping some who have already done this will chime in and we can document this for others as well.
