Vintage Rock Tumbler Parts
What We Do and Do Not Sell
We sell parts for some of the current-model rock tumblers manufactured by four companies: Thumler's, Tumble-Bee, Lot-o-Tumbler and Lortone.
All information that we have about parts for other tumblers is written below. Please read it instead of writing to us. Thank you!
For other brands of tumblers that are still in production the best place to obtain the parts is directly from the manufacturer. Some of these manufacturers include: Diamond Pacific, Covington Engineering and Mini Sonic.
Dozens of Extinct Manufacturers
Rock tumblers have been manufactured since the 1950s. In that time dozens of companies have invented tumblers, manufactured them, and then went out of business.
It is impossible to get parts for most of these tumblers.
Every week several people write to us asking about parts for extinct tumblers. We always write back with this message:
“We are sorry. We do not have them. We can only recommend the parts that we sell for the tumblers specified by the manufacturer.”
If you need a belt for an extinct tumbler, you might be able to find a similar-size belt at Stock Drive Products. They also sell bearings, pulleys, motors and other drive train parts. They have illustrations on their website to assist with belt sizing. Grainger is another source of stock motors, belts, pulleys and bearings.
Auction, Yard Sale & Flea Market Tumblers
Lots of people purchase old rock tumblers at online auction sites, flea markets and yard sales. They think that they made a great find. Then, when they try to run the machine they discover that the belt is old and cracked, the motor is worn out, and the bearings are in bad shape.
Most of these tumblers never get back into action. Why? They need an impossible-to-find part. These tumblers end up being resold and resold again because the buyer can't find the parts needed to get them running again.
We have seen the same vintage tumblers offered on Ebay by several different sellers. They couldn't find a part so they sold the inoperable machine to someone else, who couldn't find a part and sold it to another person who could not find a part… you don't want to be the next guy in that chain.
You Are Out of Luck If....
If you purchase a tumbler that is not in current production then finding parts for it is going to be very difficult or impossible. Some popular brands of extinct tumblers include: Scott-Murray, Rapco, Hillquist, Little Gem, Victor, Star Diamond and many others.
We don't know anyone who sells parts for these tumblers.
