For most of my carving points, up to about 600 grit, I use those
made by Lasco in California. the usual disclaimers, I have no
affiliation with them etc, just like theri stuff.
my best luck for polishing (1200, 3000, 8000,14000, 50,000) points
is to make my own. I punch leather disks, roll them through the
rolling mill to make them dense, drill holes, mount them on a
mandrel, coat with crazy glue, press into diamond dust of the select
grit, dry with some ventilation under a heat lamp, then use with
oil. I also use toothpicks, matchsticks, diamond paste, diamond
dust, and whatever else I can think of.
for larger carvings, i also use a diamond pacific titan. also an
ultratech faceting machine, depending. Also have 3 machines I've
made myself, for which no commercial counter[part exists, so I am
not sure what they should be called.
And,.. when all else fails, cuss.
