5.1. Preparing the Barrels

1. Select Materials: Choose materials suitable for tumbling. Harder materials like flint or quartz are generally recommended. Avoid soft or porous materials that may degrade quickly.
2. Load Barrels: Fill each barrel approximately 2/3 to 3/4 full with your chosen material. A variety of stone sizes can improve tumbling action.
3. Add Grit/Polish: Follow the specific instructions provided with your tumbling grit or polishing compounds. Ensure the correct amount of water is added to create a slurry.
4. Seal Barrels: Ensure the barrel rim is clean. Place the rubber gasket and lid securely on the barrel. Tighten the securing nut firmly but do not overtighten. Proper sealing prevents leakage.
