I've already got a 1-ton arbor press that I'd like to use for press-fitting frets. I was going to order Stew-Mac's arbor press caul, but noticed that there is a fitting on the bottom of the ram, which the caul attachment fits into and secures with a set-screw. I contacted Stew-Mac to see if they sold the fitting seperately, but they were zero help, saying their arbor press is custom made for them and their fitting won't work on other presses (total bulls**t I think, since every 1-ton press I've seen has a 1" ram like mine). I've looked at Grainger's and a couple of other industrial supply sites, hopin to find an off-the-shelf fix, but since I don't know the technical term for the fitting, it's like looking for a needle in a haystack. Any ideas on where to find this fitting, or ideas on how to manufacture one, or possibly a work-around that wouldn't require a fitting at all? Any ideas are appreciated.
