I have a real hydraulic press (25 tons), so I'd like to try to make some dies for it rather than throw money at pricey dies that are meant to work with hand-operated presses (I have both a CNC mill and a manual lathe and I'm fairly confident in my ability to get the job done). That being said, I've never done *any* metal swaging in the past, so I'm unclear on the sorts of tolerances and slack on the die internals that would be needed for swaging. Does anyone out there have schematics for their swaging dies that I could try to machine?
