For larger tumbling needs, this kit contains 5 pounds each of 80, 220, and 600 Silicon Carbide grit, plus 1 pound of Micro Alumina polish. This kit will polish 35 to 40 pounds of stone.
4-Stage Grit Progression
Run each stage in sequence. Rinse the barrel, rocks, and all media thoroughly between stages to avoid cross-contamination.
| Stage | Media | Days |
|---|---|---|
| 1 — Coarse shaping | 80 Silicon Carbide Grit | 7 days |
| 2 — Medium smoothing | 220 Silicon Carbide Grit | 7 days |
| 3 — Fine pre-polish | 600 Silicon Carbide Grit | 7 days |
| 4 — Polish | Micro Alumina Polish | 7 days |
Times are guidelines. Check progress every 1–2 days and adjust based on how your specific stones are shaping up.
Loading the Barrel
- Fill the barrel approximately 3/4 full with stones before adding grit and water.
- Add water until it just reaches the top of the stone load — do not overfill.
- Use the grit sparingly; 1 TBSP per lb For Silicon Carbide, 0.5 TBSP per lb for polish
- After the 1st stage add filler to bring the level back to 3/4 full
