Here is a tip to get your rotary tumbler moving again from @axandapple - “I’ve had my tumbler for many years and recently the barrel stopped turning.  The rod was still turning but the barrel only moved in small short spurts.  I did some quick googling and found it's a common occurrence with age.  Simply put a rubber band or 2 around the barrel to get better traction on the rod and the problem is completely fixed!” I have this same Lortone tumbler and am definitely going to try this!! I would love to hear from people with other tumblers that give this a try! #jewelrytumbler #jewelrytumblertips #rotarytumbler
