Rock Tumblers for Polishing Stones

evans 6lb double barrel rock tumblers

Rock Tumblers have been used for many years to make smooth, shiny polished stones from rough rocks. People tumble pebbles they find on the beach or bits of other rocks they find when out and about. Then there are those that only tumble semi precious rough rocks like Amethyst and Carnelian to name a few. But whatever you are tumbling, in the end you are asking a machine to do in weeks what it takes nature thousands of years to do. Just think about it, how long did it take the sea to smooth out those pebbles on the beach? Rock tumblers do the same thing over several weeks and your stones are polished at the end as well.

These machines come in many different sizes but all operate in basically the same way. Your rough rocks are placed into a barrel along with silcon carbide grit and water, a lid is placed on the barrel to seal it. It’s then left rotating on the machine so the stones can be smoothed out by the grit and water for around a week before being opened up again. There are usually four steps to the process including the polish.

Some machines will only accept one small barrel, others will accept a number of barrels in combination. Then you have the commercial rock tumblers were barrel capacities are measured in litres instead of pounds or grams. The latter category of machines uses special purpose built barrels, whereas the other machines for the most part, will work with plastic or rubber barrels.

You also get the choice of plastic or rubber barrels for most machines. A word of advice, we started with plastic barrels which found to be very noisy, think of the sound of heavy rain on a tin roof! We also found them difficult to get a good seal, hence we would find the water/grit leaking which is no good. Rubber barrels, although more expensive are the best choice They are almost silent in comparison to the plastic ones and much easier to get a good seal.
