Users have to follow a simple tumbling process where they just have to load the tumbler with uneven rocks, fill the tumbler with water, and then turn off the barrel to wait for the polishing to finish.

However, unlike other common rock tumblers, this one has a special digital polishing timer. The timer helps you know when the process is complete and usually tracks the entire tumbling process for nine days accurately. The efficiency of the tumbling process is so high, that with only 4 cycles, you get an almost permanent smoothness that gives the rocks a unique new shine.

The extraordinary educational value of this tumbler is what caught my attention in the first place.

To be honest, even as an adult, I am fascinated by this STEM toy. The biggest drawback is that you cannot load it beyond one pound, whereas rocks are quite heavy and the one-pound limit is reached with only a few rocks.

  • Easy to use- 3.5 stars
  • Digital timer- 5 stars
  • Efficiency- 3.5 stars

Factors To Consider

There are not many features that can be regarded as absolutely necessary to have when it comes to rock tumblers. Primarily, a tumbler sold by a popular brand like National Geographic would be ideal. Secondly, the size of the tumbler can be an important factor, depending on the number of rocks that you wish to process in a cycle. Lastly, it would also be better to check the amount of grit that a particular tumbler uses or requires before purchasing it finally.

FAQs

Q1. Can A Rock Tumbler Be Used For Items Other Than Rocks?

 Yes, you can process items like shells, glass, and coins inside a rock tumbler. However, always read the operator manual before proceeding with the processing of items other than rocks. If the guide clearly states that these items should not be loaded, then you should only stick to rocks and stones.

Q2. What Are The Best Practices For The Maintenance Of Tumblers?

The tumblers that are being manufactured these days are very sophisticated and do not require much maintenance. However, general measures like keeping the barrels clean, maintaining proper tension in the belt, and lubricating the machine once a month will benefit you in the long run.

Q3. How Many Rocks Should I Add?

The number of rocks to be added to the tumbler depends entirely on the capacity of the tumbler. Moreover, even if the tumbler allows a 3-pound load, refrain from filling it entirely with rocks so that there is some space left for processing.
