I want a CA size 5c collet holder for my lathe’s QC toolpost, so I can power-feed drills, reamers, etc. into the chucked work. MSC wants $230. Plus shipping for an Aloris, no-go for me. I’d be happy with cheap import since I’d only use this a few times a year. But I can’t find any CA-5c for under $218. Anybody know of a source? Alternatively I’d make one, maybe try boring/reaming up a $40. CA-MT3 holder, or bolting a square 5c collet block to some inexpensive CA holder. Someone here has made one already I’m sure, how did u do it?
