So you’ll want to be delicate in your tumbling process, and cut down on the time in each stage – especially stage one and two! Instead of grit, a lot of people like to use aquarium gravel and dish soap. Limit your tumbling to a few hours maximum. That’s all you need for some shiny coins! What magazines and online forums do you recommend? On the other hand, the upside of beautiful, round, shiny stones, with which to undertake any crafting project or make any household display, are agreed to outweigh the downsides.

Conversely, if you’re shopping for a kid’s tumbler, the starter kit might also make more sense. Noise Reduction Even so, tumblers are noisy, and the best solution would be to find a place, like in a garage, so that noise wouldn’t be a source of annoyance. Overload Protection
