Sorry, still getting my laptop sea legs back here. Anyhow, I want to turn the pieces down in diameter. Now, these pieces are of course "finished" (albeit pretty rough, it's a cheap Turkish set to be sure, but sooo pretty), each having a sort of neato mosaic type design embedded in the center or each piece, etc. So, it's certainly unfeasible to attach multple pieces on an arbor, as I can't make a hole in the middle without really tearing them up. So, how the heck does one go about turning down a stack of no-center-hole disks like this? About all I can come up with is a) do them individually, by chucking each in a collet (hopefully; they're a little > 1", naturally...) and taking down ~ 1/2 of the disk thickness, and then turning each around and taking the other half down...yuck... b) perhaps double-back taping them together and then a rough end piece on either end of the stack, that can both be center-drilled and mounted between centers, etc.; could "clamp" them between the centers pretty tight this way, and thus help make sure all those double-back tape pieces hang in there while turning the pieces down... c)...?
I work with a lot of optics, and in that world they wax the disks together and melt them apart after turning down...I fear I'd really mess up the mosaic'd faces doing something like that, tho.
Any thoughts would be much appreciated-- Charley Hale
