Not really sure where to post this, but here goes:
My wife makes cool looking jewelry using wooden, stone, shell and acrylic beads. She has decided that since I have all these neat tools and a lot of machine shop experience, that I should be able to drill porcelain, stone and shell, keeping her overhead down and allowing her to present more "One of a Kind pieces". The holes however are only 1.5-2mm, otherwise they hang "sloppy". While I have drilled glass, stone and porcelain using a brass tube, abrasive and water, or kerosene, I can't find any tubing small enough to make the holes she wants.
Any ideas?
