If you are serious about polishing, I would go with diamond
materials. There are velcro backed discs for air tools and I would
suggest you contact A Cut Above 800-444-2999 Steve or Gary) to see
if they have anything in an 1/8th in shaft size. Also Kingsely (Boy
I cannot find it or get a good URL for them with this name, but they
do have a lot of variety in stone tools) If you really want their
name/address/URL let me know and I will go to my shop and find a
catalog. Also a search at
will give you a number of diamond cutting tool manufacturers if you
want to try.
Or posting to a rockhounds group might get you a lot of good info.
