Product Information

This starter kit contains half of a pound of stones to try out tumbling with. One of the most interesting and fascinating aspects of tumbling, no matter what level you are at, is getting to know the mineral you are tumbling. 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.

Perfect for beginners. Easy to operate. Features an automatic shutoff timer so you can get bigger results and save energy. With all the excellently crafted professional features, you also get speed controls set to help you navigate through the best of gemstones. With the kit you get a shutoff timer to provide you with accurate results. You also get a pound of rough gemstones, four polishing grits and jewellery fastening. Alongside the instruction manual is simple to grasp too. 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. The last important piece of any starter kit is the abrasives. This kit comes with a small amount of abrasive, enough to take the sample minerals through each step of the process. The motor spins a pin on the bottom, which turns a hard rubber barrel through friction, while the end of the barrel is held in place by a pin. This design differs from the Lorton 3A in how the motor is cooled and the structure of the base of the tumbler is sturdier.

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. 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. It has a similar design to the Lortone 3A – that we have found to be the most efficient design on the market.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. It’s great to have this small amount of abrasive as a starter because it lets you see a typical process before you choose how you want to conduct your own tumbling processes. Now that you’ve decided on the ideal barrel size, you need to decide on the tumbler type. Rotary vs. Vibratory Tumblers 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. 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.

Their products work as described and you will never have to try to see through pounds of marketing façade to the real product. 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. 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 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.

🍪 Privacy & Transparency

Rotary tumblers take much more money to produce better results. Vibratory ones don’t need any extra upkeep once you get it set up! 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 The 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. Some people choose 3 or 5 steps for their tumbling process, and some change the process depending on the stones. Because grit abrasive is usually only found in bulk, this small amount is a much appreciate sample.
