About this deal

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. The 1-lbs. capacity is rather small, but beginners and children might still find it suitably sized. It all depends on your need and the way in which you intend on using the machine. The instructions included by the manufacturer can be really helpful if you’ve never used such a machine beforehand. Plus, the fact that it is lightweight comes as a pro, since you can easily carry it around – even children can do that effortlessly. 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

While not as cheap as some tumblers on the market, it’s much quieter, longer-lasting, and just works better than cheaper models. In other words, the extra value gained by paying a bit more for a budget tumbler is well worth it.

The instructions also contain fun facts about each mineral and information about how the tumbling process works in relation to how the natural process of smoothing and rounding is carried out. 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. 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. On the other hand, the unit is a bit loud. While this isn’t necessarily an engineering fault, it can be an annoyance to some people. This also depends on the place where you plan on using the machine. If your insulation is decent, then you shouldn’t be too bothered by this. Lortone is a family-owned business based out of the Northwest. Like many smaller companies in the giant lapidary field, everything about them is face value and no-nonsense.Plus, since you get nine types of different gemstones, you can really get to work the minute after you unbox the machine. So, if you’re eager to give it a run, this is great. At the same time, we noticed that the unit has the tendency to overheat. Therefore, it might be recommended to pause the machine every now and then. It goes without saying that this will make the polishing process last more than you’d want. Buying Advice A TUMBLER THAT'S MADE TO LAST - The durable motor has time and speed control settings so you can set it, and forget it. An improved, leak-proof barrel features a stainless-steel lid is 75% quieter overall than plastic tumbler barrels. When you buy it, this model includes a moderate amount of grit to try out the standard 4-step process and the abrasives to go along with it. It also comes with oil and a wrench to facilitate working with the equipment – a clear sign that this tumbler is built for the long run.

Therefore, I want to give you a few rules of thumb to choose an affordable option without sacrificing too much quality. Their products work as described and you will never have to try to see through pounds of marketing façade to the real product.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.
