Rotary versus Vibrating Rock Polishing - Tom Kuzia

One of the worse things a "newbie" to rock tumbling can do is to buy a "bargain" tumbler. The belts break often, the motors burn out, the barrel seals leak and the friction bearings on the rollers wear out in a hurry. I know that money can be a deciding factor, but consider buying a car with bald tires and starting out on a cross country trip.
