I just drilled some of the original imitation stone block from R&T research, I tried on one of the Turquoise and like a fool I tried to drill through the first blank, of course it fractured when the drill exited, Next blank I drilled 2-1/2 deep and cut off the undrilled parts of the rest, the I cut the blanks about 3 inches long I’m using reasonably good drill bits 25/64 Cleveland Latrobe we drill stainless and tool steel with them every day, I did notice that even drilling with water that some of the urea or polymer stuck to the bit, I guess next batch I’ll try some with Ti coating, I drilled them at different speeds, enough I getting less drill heat at about 450 rpm it’s hard to tell what the speed are our drill press is turning it’s a 30 year old Powermatic varispeed and the numbers on the dial are worn off,
I wish I didn’t have so much of this stuff, I'd like to try the new pliable material, but I've got about 30 pounds of end cuts from a lapidary job I did a few years back, the client was too cheap to use real stone, the stone will drill but turning should be a lot of fun, I ordered some cigar and the euros that use the parker refill kits from Berea since apparently they are about the only one no one has complained about their plating pitting, although I've not had any trouble with the people I buy from as far as their plating but not pleased with other aspects
Any body has any experience on turning the older trustone /Imitation stone they would care to impart, hopefully meaningful information?
I’ll be turning it in a jet 920 metal lathe, that is beginning to think it’s a wood lathe that lost it’s tool rest, got the print drawn up for one just seems easier to turn dials than hold those long scary sharp things, which I don’t think would work on this stuff any way
