Note: It is imperative to load the Tumbler with the proper amount of materials, or the process will not be successful, and the motor could be damaged.
First Grind, Pre-Polish, Polish and Burnishing First Grind: Run the Tumbler for 24 hours, checking for gas build-up at the first twelve hours. Slowly open the Barrel Lid, releasing the small amount of gas that builds up during the process. Check the stones, they should show slightly rounded edges. Clean the seals and close the Lids. It is important to release the gas, otherwise it will thicken the abrasive slurry. After another 24 hours check again. If the slurry is thickening, add a little water.
Notes to remember: 1. Always clean Barrels and stones between steps. 2. When polishing or burnishing use plastic pellets (they will wear out during use). 3. Use a log book to keep track of each step. 4. If starting with stream-worn or smooth stones, you may be able to eliminate the first step. 5. Purchase a mineral book which details selection of stones for tumbling. As you learn about relative hardness of each stone you will achieve greater success by not mixing soft and hard stones. 6.
