[Lokking 4] Used faceting machine

Wanted: used faceting machine.

I’ve been doing the precision cuts by hand, and am able to hold
0.0005" rolerance, but it is time consuming.

Prefer ultratec IV, or graves.

Mark ! What have you been cutting to a .0005 tol.by hand and how are
you checking it and with what ? I am a retired Toolmaker and Gage maker
and worked in the .ooooo but not in my rock shop. i also do Faceting
and have sence 1954. Try Ebay there is several facet machines on there
that belong to guys on Faceter Digest. Bill D. in the backwoods of east
Texas

Holding 1/2 of a thousandth of an inch may sound impressive, buy with
some time, a good calipers and an optivisor it is not too hard to do.
Did a geometrically perfect hexagon out of lapis, just to see if I
could do it, a double sided cab wth a full curve on both sides and an
almost undetectable meeting line.

Overall, took about 2-1/2 hours in 3 sessions. By hand, no jigs.

Hey, if you can’t turn out a perfect stone every once in a while for
fun, after 25 years of cutting,
