After a several year break from tumbling, caused by an addiction to gold prospecting, I decided to run a batch of stones. It it a mixed batch that were all from my mining tailings in Oregon and California near Brookings. It has a little of everything, jaspers, quartz, agates, obsidian, and a bunch I can't ID.
My three rotary tumblers decided that there were not going to run again (Harbor Freight), so I decided to convert my Frankford Arsenal case tumbler over to rocks by gluing a piece of rubber hose over the threaded shaft. I new nothing about vibratory tumblers for rock, so I started out with one day in 60/90 (and then read not to), two days in 220, two days in 500, and two days in cerium oxide. The rocks were burnished in between with borax. Both ceramic balls and plastic pellets were added. They turned out great considering all of the mistakes I made in the process and the crappy tumbler. Critiques welcome.
