Rock Tumbler Barrels


Click on a barrel for more information.

We sell replacement barrels for all of the tumblers that are sold on our website. Many people who tumble buy an extra barrel and use it only for the polishing step. No grit goes into that barrel - only polish. This helps prevent grit contamination during the final polishing step. Other people clean the barrel and stones by tumbling their stones for 24 hours in a thick soap solution made with Ivory bar soap and water to clean both the stones and the barrel.
