I have been following the disccution on tumbling jewlery.
What type of tumbler should I use? <<
Basically there are 3 types of tumblers; the barrel type, the
now the magnetic. In terms of time required to polish the barrel
is the slowest & the magnetic the fastest.
The only time polishing (burnishing, really) occurs is when the
media is impacting on the work. In a barrel, this only occurs
when the work has reached the top of the media & slides down to
the bottom. In vibratory & magnetic tumblers the media is
impacting the work 100% of the time.
The vibratory tumblers can also make use of a flow through
system which continuosly recirculates the liquid used as a
cleaner & lubricant. The foreign solids are filtered out before
returning the liquid to the tumble r.
Vibratory tumblers come in all sizes, from some that hold about
2-3 quart s to really big industrial units. Rio Grande sells all
I've been using the smallest vibratory with about 7 1/2 lbs of
assorted shot for about 7 years. It's done everything I've asked
of it. It cost about $75 when I got it. The shot was $5.00 per
lb. Shot is available in
carbon or stainless steel. Stainless is more expensive. If you
go to a shooting sports store you can probably get the same
tumbler for less. The
reloaders use them to clean their brass before reloading.
