Hey guys, I ended up with a 6 1/4" Cushman 6766 6-jaw lathe chuck that looks to be in good shape, but it won't fit my Craftsman 12x36 lathe. Any idea what mount this uses and what it's worth? I'm trying to sell or trade my lathe for one with a larger spindle bore, so I may keep this if I end up with a lathe that it will fit. It has a 1 3/8" bore and six 7/32" holes around the center. It only has one wrench hole and four equally-spaced 3/8" or 7/16" threaded holes around the circumference (too lazy to go measure).
