Factors to Help You Buy the Right Rock Tumbler for Your Kid

·      Barrel Capacity

Various rock tumblers for kids have differing barrel capacities, usually indicated in weight (lbs.). Many rock tumblers for casual use have a capacity of 1- 6lbs., while those for professional use can have a higher capacity.

Since barrel volume dictates the number of stones your kid can polish at a time, we suggest that before you purchase one, make sure that it can tumble enough rocks for your kid’s specific needs.

For newbies and kids who just want to pass time, purchase one with a 1-3lbs barrel. If your kid is more about rock tumbling, shop around for a rock tumbler with a barrel capacity of 4 or more lbs. Such a generous volume will help them polish enough stones at a time.

·      Noise

While rock tumblers are a great educational toy for kids, the noise arising from the tumbling process can be a real nuisance if you stay in an apartment or a small house without a designated place for rock tumbling.

Therefore, before you purchase one for your kid, make sure that it operates silently. Probably, you should shop around for a unit fitted with a rubber barrel to absorb excess noise and vibrations.

Also, you can search around for a rock tumbler with plastic barrel and sound cover to minimize excessive noise. A noisy stone tumbler can discourage your kid from ever using the unit for a second time.

·      Construction and design

A rock tumbler’s construction and design is another crucial factor to consider when looking to pick the best from the thousands of rock tumblers in stores. If you want a unit that will survive for years, we propose that you invest in one constructed from premium grade plastic or metal.

If you are buying a rock tumbler for your kid who is starting, we recommend that you invest in a unit that is easy to operate or one with a detailed instructional manual to guide your kid through the tumbling process.

However, if your kid has some experience in rock tumbling, don’t shy off from buying a unit with advanced features like an inbuilt timer that turns the unit off after a predetermined period and or a speed regulator to control the unit’s rock tumbling power.

·      Check out the extras that come with a rock tumbler.

Many best rock tumblers for kids don’t come alone. But, they come with multiple accessories that your kid will need during the rock tumbling process. For instance, some come with different types of rocks to be tumbled, grit to accelerate the rock tumbling process, and polish to give tumbled stones a lustrous appearance.

Additionally, some best rock tumblers for kids come with oil to lubricate moving parts, a guide to introduce your kid to the basics of tumbling and geology, as well as spares to replace worn out parts.

Thus, if you want good value out of your dollar, look around for a unit that comes with several extras to get your kid started without buying any other rock tumbling accessory separately.

·      Budget

Ideally, stores have a rock tumbler for every budget. However, rock tumbling experts commend that you steer clear from lowly priced rock tumblers. Why? Most are designed from cheap components that can hardly survive when subjected to substantial and regular rock tumbling projects.

·      Intended purpose

Who are you buying the rock tumbler for? Are you buying it for a first-timer who is yet to develop an interest in geology and rock tumbling? If yes, go for a small-sized and affordable rock tumbler instead of an expensive one.

That way, you will not regret buying one just in case your kid doesn’t develop an interest in rock tumbling.

In case your kid has already developed a strong passion for rock tumbling, shop around for a powerful, durable machine that would keep them inspired, as well as last for a reasonable period. Basic models would discourage them or even wear out quickly if your budding geologist subjects them to heavy use.

Take Away

As can be seen, the market has lots of best rock tumblers for kids. While they all come with a promise of being durable, silent, and easy to operate, not all can live up to this promise. A majority of them are likely to let you down.

For that reason, we picked some of the best rock tumblers for kids that stores have to offer. Our picks have an excellent customer score on amazon and other independent review sites, they are designed from premium grade materials to last, and they are powerful enough to run the whole day long for several weeks.

Moreover, our best rock tumblers produce less noise and vibrations. Operating them won’t be a nuisance to family members or your neighbors. We hope that you found a suitable model for your kid who is looking to start or advance their passion for rock tumbling.
