Thumler's Model A-R12 Rock Tumbler
This is a rock tumbler for the experienced person or for the beginner who has access to lots of rock. The metal frame and heavy-duty, maintenance-free motor easily turns the twelve-pound barrel (can also be converted to run two Thumler's three-pound barrels).
The Model A-R12 has a single 12 lb. rubber barrel. If you fill this barrel about 2/3 to 3/4
full of rock as recommended it will process about nine pounds of rock. The soft rubber barrel will
tumble your stones with a minimum amount of noise.
The tumbler is supplied with an instruction book that will guide you through tumbling your first
batch of rock. You will also receive an email address that you can use to ask any questions
that arise as you begin tumbling.
We want you to enjoy this hobby as much as we do. 
For Best Polishing Results:
If you are really serious about getting a high quality polish we recommend getting a separate barrel and using it exclusively for the polishing step. A dedicated barrel for polish (and a thorough cleaning of your rocks after the 600 grit step) will help avoid grit contamination of your polishing step. |
