Have you looked into the new magnetic tumblers on the market? They use
magnets and very fine stainless steel needle sized media to get ito even the
smallest, tightest recesses. I think Swest carried one or two different
sizes of tumblers. Also, this months AJM mag has an artical on mass
finishing which give s quick overview of magnetic tumbling.

I would be very interested in treatment info on the Morro Redondo material,
per your response to a post from Tony Ruyter.
And here’s another potential topic for discussion: can anyone impart specific
on stripping precious metals after casting? I’ve found that many
intricate castings simply can’t be polished any other way, and I’ve done a
fair amount of electrostripping with cyanide and a compound sold under the
tradename Tivabrite. But, frankly, working with cyanide really bothers me:
who knows when one might encounter an acidic substance and generate the
dreaded hydrocyanic gas? And I haven’t learned of any effective way to
neutralize it prior to disposal. I’ve tried a couple commercial preparations
that claim to be cyanide-free strippers but haven’t found them to be
effective. Perhaps I’m using too low an amperage. Any experienced strippers
out there? (Hey, this could be interesting!) Thanks, Rick.
