[Source] using a lathe to grind lapidary materials

Aloha Mark, Try to contact, the “Gryphon Corporation” at 101 East
Santa Anita Ave.; Burbank, CA 91502. There phone was (818)
845-7807. They have some unique lapidary tools, like a diamond
wire saw, diamond bandsaw, and yes, a diamond lathe (among other
things). They used to regularly advertise in the “Lapidary
Journal”, but haven’t seen an ad in a while. Glenn Lehrer used
to do ads for them, as a customer/spokesperson. Worth a phone
call, nice tools.

Best Regards,
