Rock Tumbler

I use a rotary polisher, to polish my pen clips and rings. Stainless Steel shot, water, and a couple of drops of dawn.
Polishes up my silver, bronze and nickel-silver quite well.
 
Would 3 or 4 (or 10) fattish orings on the shaft give enough friction?
Possibly. But they might also walk (crawl?) over to one end over time. I've read it can take two weeks 24/7 to do the initial roughing with coarse grit.
Now fat Orings with 3D printed spacers would work perhaps. But then at the moment I'm expecting tubing via Amazon sometime today. Try that first.

I have a vibratory tumbler from PA that I haven't unpacked yet for castings. Mostly since I haven't cast for quite some time.
