Parts for Vintage Rock Tumblers
What We Sell
We sell parts for rock tumblers manufactured by two companies: Thumler's Tumblers and Lot-o-Tumbler.
What We Do Not Sell
If you need parts or an owner's manual for a tumbler made by another manufacturer, please contact the vendor who sold you the tumbler. If that vendor is out of business or does not have what you need, please contact the manufacturer of that tumbler. The box or the papers that came with the tumbler usually have contact information for the manufacturer. To help you, we have prepared a list of existing rock tumbler manufacturers.
Generic Belts and Motors
If you need a belt or other part for a rock tumbler that has outlived its manufacturer, you might be able to find something that will work at Stock Drive Products. They sell bearings, pulleys, motors, shafts, and other drive train parts. They have illustrations on their website to assist with sizing. Grainger is another source of stock motors, belts, pulleys, bearings, and other parts. These companies do not sell "rock tumbler parts". They sell generic parts used by manufacturers to build and repair a wide variety of machines.
Rock tumblers have been manufactured since the 1950s. In that time at least 100 companies and countless basement manufacturers have invented tumblers, manufactured them, and then went out of business. Some of these companies no longer exist.
It is nearly impossible to get parts for most of these tumblers.
Every week several people write to us asking about parts for extinct tumblers. They want to know if we have belts, barrels, gaskets, lids, etc., for their tumbler. We always write back with this message:
"We are sorry. We do not have parts for your tumbler. We are unable to direct you to a company who stocks replacement parts for your tumbler."
Before You Buy A Used Tumbler
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.
Many 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 used to collect early rock tumblers and watched for them on eBay. We have seen the same vintage tumbler offered on eBay by several different sellers. The first seller was getting rid of the machine. The first buyer received the machine and could not get the part, so he resold it on eBay. The next person bought it, could not use it, and put it back up for sale on eBay. You don't want to be the next guy in that chain! We have been there!
You Are Out of Luck If....
You are out of luck if you purchase a tumbler that is not in current production, because finding parts for it is probably going to be very difficult or impossible. Some popular brands of extinct tumblers include: Rapco, Hillquist, Little Gem, Victor, Skilcraft, Star Diamond and many others.
We don't know anyone who sells parts for these tumblers.
