Product Information

To reiterate, the Lortone 3A wins because of its all-around value. Its simple, no-frills design affords it a reasonable cost while allowing the motor to run for years. Its hard rubber barrel ensures it’s among the quietest of the rotary tumblers and is made for at-home use. It goes through such a transformation in color, shape, texture, and clarity from its raw shape to its tumbled shape that it is interesting to know the “why’s” and “how’s” of the mineral to see how they affect the tumbling process.

Because they involve fewer collisions, vibratory tumblers will change the shape of your raw stones less than rotary tumblers. Rather, they smooth the stones out in the general shape that they started in. It has a similar design to the Lortone 3A – that we have found to be the most efficient design on the market. At the same time, the smart engineering prevents leakage incidents, which is just as important. For instance, as the machine functions on its own for weeks, leakage incidents could easily go unnoticed, which is why this feature is of great importance.

Therefore, I want to give you a few rules of thumb to choose an affordable option without sacrificing too much quality. Concurrently, the fact that you get a complete, comprehensive kit is another thing we like. In fact, this makes the unit a great idea for a present. What We Didn’t Like All the moving pieces are sealed tight and the motor is not easy to access for curious hands. It also has an automatic shutoff timer since it is relatively easy to forget to stop and reload the tumbler. Parameter

Mechanical parts break, that is just a fact of life. A sign of a tumbler that is built to last is that it will come with some spare parts, such as rubber belts connecting to the motor or a wrench. Now that you’ve decided on the ideal barrel size, you need to decide on the tumbler type. Rotary vs. Vibratory TumblersThe Lortone 3a has a VERY quiet rubber barrel that has a 3lb holding capacity. And the best thing about the Lortone 3a was just how unbelievably quiet it was. Another telltale sign is if you see a lot of people online asking for replacement barrels. Of course, this can just mean that the barrel is low quality, but it more often means that the main mechanical construction outlasts many barrels.
