I saw this a while ago, but keep forgetting to mention it.
I don’t know if it is inexpensive, but Beader’s Digest (formerly
Lapidary Journal) has an ad for a “Magnetic Barrel Finishing
Machine” by a company called Imahashi.
The ad text says:
“Workpieces are tumbled together with the magnetic media through
the rotation of the magnets. Different theory from the
traditional method. Jewelry mountings, precision machine parts
can be easily deburred and polished. An excellent surface
finish is obtained in a short time.”
The ad goes on to promise:
– Simple to operate
– No handwork needed
– Crean, (sic), dust free
– No material removed
– Abrasives seldom used
– Delicate parts uniformly polished

(I hope this isn’t the same one everybody has already been
discussing. If it is, please pardon the waste of space!)
