I have a crisis! For 15 years I have been using a rubberized
abrasive cone for prepolishing inside of cast rings. This goes on the
tapered spindle of the polisher like a felt cone. These were made in
Italy and I got them from Rio Grande. These are great. In just 60 to
90 seconds I can buzz off the inside of a ring with the 100 grit cone
and then have it all set to go to a felt cone.
Today I called to order some more and Rio tells me they are
discontinued by their supplier. I have not seen any other jewelry
supplier offering anything like this. Any suggestions for
alternatives? I am desperate. These have worked so well for so long
that everything else available seems like a step backwards.
