     • Runtime recommendations for coarse grinding (typically the longest stage).
     • Regular inspection of the rocks and grit.
     • Proper disposal of slurry (environmental considerations).
   • Step 3: Medium Grinding Stage:
     • Cleaning the rocks and tumbler thoroughly.
     • Loading the tumbler with rocks, medium grit, and water.
     • Runtime recommendations for medium grinding.
   • Step 4: Fine Grinding Stage:
     • Cleaning the rocks and tumbler thoroughly.
     • Loading the tumbler with rocks, fine grit, and water.
     • Runtime recommendations for fine grinding.
   • Step 5: Pre-Polish Stage:
     • Cleaning the rocks and tumbler thoroughly.
     • Loading the tumbler with rocks, pre-polish grit, and water.
     • Runtime recommendations for pre-polish.

     • Inspecting the rocks for imperfections and considering another polishing cycle if needed.
     • Methods for enhancing the shine (e.g., using mineral oil or rock wax).
5. Troubleshooting Common Issues
   

   Problem	Possible Cause	Solution
   Rocks are not getting smooth.	Insufficient grit, wrong grit type, tumbler not rotating properly.	Add more grit, use a coarser grit, check tumbler motor.
   Rocks are cracking or chipping.	Rocks are too fragile, tumbler speed is too high, rocks are hitting each other too hard.	Choose harder rocks, reduce tumbler speed, add more ceramic media.
   Rocks are not getting shiny.	Incorrect polish, contaminated polish, insufficient polishing time.	Use the correct polish, ensure the tumbler is clean, extend polishing time.
   Slurry is forming excessive gas/pressure.	Certain minerals react and produce gas.	Burp container/tumbler to release pressure.

6. Safety First: Important Precautions
   • Handling Heavy Rocks: Emphasize proper lifting techniques to avoid back injuries.
   • Working with Abrasive Grits: Remind readers to wear a dust mask to avoid inhaling fine particles.
   • Electrical Safety: Ensure the tumbler is properly grounded and that electrical cords are in good condition.
   • Supervision: Discourage leaving the tumbler unattended, especially when children or pets are present.

So, grab your favorite rough stones, get that big rock tumbler humming, and prepare to be amazed by the beauty you can unlock! Happy tumbling!
