Product Information

Size and capacity: Consider the size and capacity of the tumbler. A smaller tumbler may be suitable for children or beginners, while a larger one may be better for more experienced users. No Ceramic Media Filler – It doesn’t come with ceramic media filler so you would want to get that in addition ( this is the one I use). Reverse Setting– It has the ability to reverse the direction of the rotation so it gives more flexibility in the settings.

No Grit – This polishing kit skips some steps by jumping directly to polishing instead of slowly grinding and then polishing so stones don’t come out as smooth and shiny. 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. 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 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. Rotary Tool: The Dremel rotary tool is the core of the kit. It’s a handheld power tool with a rotating tip that allows you to attach different bits for a variety of tasks.

EASY TO USE - digital 9-day timer (with automatic shutoff feature), 3 speed settings, beautiful LCD screen. While rotary tumblers allow you to change the shape of the stone vibratory ones are best in polishing. The body that contains the motor is made of metal, which protects the motor much more effectively than plastic 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.

Polly plastics grit and polish are better than the grit provided and gives you a larger amount of grit - the tumbler has been running for about 2 weeks and is still working amazingly It comes with detailed instructions on how to use the levels of grit from coarse to the final polish, which provides a great learning experience for kids the speed is great but it still takes about 3-4 weeks to fully complete the tumbling process including grit and polishingThe powerful, heavy-duty motor with the leak-resistant barrel runs quietly. The rubber material reduces the noise level, and the durable motor is sturdy enough to tumble rough stones for years to come. Powerful quality: Runs on a powerful heavy duty motor that will last for a very long time, and includes a leak-resistant barrel that runs quieter than the other brands. 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. Easy to Open– This is one of the easiest barrels to open as it comes with a washer that you use to lift the lid.

Good Slow Speed– The slowest speed is not too fast so it can still be used as an every day tumbler.

Easy to Open – This is one of the easiest barrels to open as it comes with a washer that you use to lift the lid. Information on Stones– The booklet includes some fun information about the stones included in the kit Ceramic Media Filler or Plastic Pellets (if your kit doesn’t come with some) – I prefer ceramic and this set comes with the grit and ceramic. You can also get the ceramic on its own from here. Only One Speed– There is only one speed to this machine, but it spins at an appropriate speed to get a professional polish.

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.

Clear Barrel– The clear barrel lets you get a glimpse at what’s happening without having to open the lid, which can be fun to watch. No Filler– It doesn’t come with any filler so the stones aren’t protected throughout the process, leading to broken or very small stones. It is extremely easy to clean I just rinse the tumbler in my sink for about 30secs. Then dry it off with a paper towels and it’s ready to go 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.
