Review: Great value and wonderful product - 15lb tumbler and from a company that has been around for ages. My first Thumler Tumbler was bought for me about 1968 and it still works great today. I have only had to change drive belts after all these years. The new tumbler I bought for larger processing size. One thing to note for people not familiar with tumbling in general. this tumbler and any rotary tumbler are made for softening and rounding the stones and do so by the hexagonal barrel causing the material to move more with the grit and becomes a more aggressive tumbling process than a vibratory tumbler which is more designed for polishing than shaping a stone. That is why polishing such as ammo brass and other polishing is done with vibratory tumblers. If you only want to polish a stone that is already smooth then go Vibratory and Thumler's Vibratory tumblers are equally as well built as I own those also. PROs: 1) The heavy steel construction, it will last a lifetime 2) Rubber Inner Barrel cuts down on the sounds of tumbling. If you've ever heard a cheap tumbler with a plastic barrel you know what I mean - won't name names but buy quality not cheap junk. 3) Inner Barrel and lid gasket are replacable if you ever have to and they are not expensive. 4) Same strong motors they've used for generations and they just work! 5) Inexpensive rubber drive belt you can buy anywhere and they all work 6) Torque. The motor can drive heavy loads with ease. Cons: None really but one suggestion Only one and it has nothing to do with the tumbler but a person preference. I would much rather have a round knurled nut instead of wingnuts for the lid hold downs and maybe some rubber track on the bottom of the unit. In place of the missing rubber feet I just place the unit on an old shop towel to not have the vibration of the unit transferred to the concrete making it even quieter. I would buy one of these any day of the week. They work great!
Review: Great product! - Love this product. It runs smoothly and quietly. I have mine on a piece of flexible insulation (K-flex eco) on a tile floor on concrete. I say all of that to say that it is almost silent, you can barely hear the rocks tumble. I had it directly on a wood cabinet and you could hear it 50 ft. away. So if you are having problems with the sound I would just change the location. It is built out of very thick steel and around 1/4 in rubber as the lining. The lid has a little bit thinner rubber, and wing nuts that are easily replaced at your local hardware store, but mine haven't worn out. I may post some pictures of polished rocks, but don't really see the point they are indistinguishable from ones that you can find at a souvenir shop. The motor is pretty cheap (I am an electronic technician), but built rugged, so although it is single speed and not very efficient it should last for years as long as you keep the dust out. The belt on mine hasn't worn at all after several months. The only parts that have seen any wear are the red paint where the drum sits on the drive shaft (from getting grit on it after changing to a finer grit), and the rubber guide piece on the drive shaft where it keeps it straight.

### ⭐⭐⭐⭐⭐ Great tumblers
*by A***S on December 21, 2024*

I had already purchased 2 of these, and really love them. So I ordered another. Having 3 of these and set up in the garage makes tumbling more fun and speeds the process up a lot. These tumblers are built to last, but you must keep them clean to prevent any future problems. Would recommend these products.
