I got a new Aubin rotary tumbler a few weeks ago and really love it,
as an upgrade from my old tumbler. For those who aren’t familiar, it
has a unique “diamond” shaped barrel (almost the shape of a typical
alcohol lamp) and it rotates around its central “point.” The barrel
is a translucent plastic.
I’ve always used stainless shot with my silver pieces, which is
primarily what I thought I’d use this tumbler for. But it’s been so
nice (and quiet!) that I thought I might try some of the dry
polishing media, like rouge-charged walnut shells.
My question . do I need to have a separate barrel for that type of
media? I’d assume it will leave a rouge residue on the inside of the
barrel, right? Will that rouge residue mess up my stainless shot? Or
will a simple wash/wipe with an ammonia/soap mixture clean the inside
sufficiently for use?
