Good question - I'll be watching this thread! I'm fairly new to
the wonderful world of tumbling, so I can only contribute an
I have a cheap little Harbor Freight tumbler, which works
beautifully with stainless shot, but I also wanted to try a
final-finish media, so I ran a batch of cast pendants with some
green Rio Sunsheen media. After about 36 hours, I couldn't really
see a marked improvement in the finish, so I emptied out and washed
the tumbler barrel and ran a new batch of pendants in the usual
soap, water, and shot. To my horror, the pendants came out
thoroughly coated with sticky black goo, which would not wash off
and had to be removed with Semichrome on a muslin buff. Of course,
this all happened right in the middle of a big rush order, so it was
a real pain in the tuchis.
After a good cleansing with the amazing flat Coke, the tumbler was
restored to its normal function and everything was coming out bright
and shiny again. All I can figure is that it maybe had something to
do with the barrel itself, which is made of heavy black rubber with
an appallingly phenolic smell that never quite wears off. I know
some of you fellow Orchidians must have the same tumbler; have you
encountered this weird problem?
I've been thinking of running a cycle with the final finish media in
a plastic Skippy jar, which just happens to fit the tumbler's
dimensions perfectly. Any thoughts?
