Product Information

Perfect for beginners. Easy to operate. Features an automatic shutoff timer so you can get bigger results and save energy.

While rotary tumblers allow you to change the shape of the stone vibratory ones are best in polishing. 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. Rotary tumblers take much more money to produce better results. Vibratory ones don’t need any extra upkeep once you get it set up! 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 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.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. Always look for simplicity and rubber connections in these openings. Not only will they make your life much easier and cleaner, but they will also signal a higher quality product. Therefore, I want to give you a few rules of thumb to choose an affordable option without sacrificing too much quality. 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.

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 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. 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. 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. 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. 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
