This is the Lortone 3a Rock Tumbling Kit.
In four easy steps, this professional-grade tumbler will haveyour jewelry,coins or stones professionally finished.
Step 1: Grinding and Shaping.
This is the most important stage in the tumblingprocess.
The coarse abrasive grinds and shapes the stonesand removes rough edges, cracks and pits from them.
To begin, open the barrel and fill with appropriately sized stones.
After the stones are placed in the barrel,add the coarse silicon carbide abrasive.
Reference the unit's instruction manualfor the ratio of weight to volume used in the barrel.
Slowly add water until the level of wateralmost covers the top layer of stones.
Carefully seal the barrel.
Be sure not to over tighten the lid, as this will warp the lid thus causingleaks.
Turn on the barrel and allow it to run for approximately one day.
After one day, open the barrel to release any gas that might potentially be in thebarrel.
Reseal the barrel and repeat this process for seven to ten daysuntil the stones are smooth and rounded.
After completing the first stage,the barrel and stones must be thoroughly washed and cleaned to remove all traces ofabrasive.
Step 2: Smoothing.
Put the clean stones in the barrel and add the appropriate amountof fine silicon carbide abrasiveand water.
Repeat the process showed in step 1, checking every two to three dayson the status on your stones.
On the 7th day, inspect several stones.
When dry,The stones should have a uniform matte finish over their entire surface.
If not, tumble for two to three days longer, or until the finish is achieved.
Clean the barrel and stones using the same procedure from step one.
Step 3: Pre-polish.
Put the clean stones in the barrel and add the appropriateamount of pre polish and water.
Repeat the process from the previous stepsand check after seven days.
Remove any broken or chipped stones to avoid scratching.
The surface of the stones should be quite smooth and have a slight shine.
If not tumble for another two to three days until this is achieved.
Clean the stones using the same procedure from the previous steps.
Step 4: Polish.
Make sure the barrel and stones are completely clean prior to this step,as contamination is the primary reason for inferior results.
Put the clean stones back in the barrel,add water in the appropriate amount of polish.
Plastic pellets can also be usedto increase the volume and soften the tumbling process.
Repeat the process from the previous steps,allowing it to run for seven days.
At the end of the polish cycle,inspect the stones.
The surface of the stones should have a bright shine.
Clean the barrel and stones using the same procedure used in the other steps.
Here is a quick summary.
One:Fill the barrel two-thirds full with your desired product.
Two: Use the correct amount of abrasive for the size the barrel and volume ofproduct.
Three: Add water until the top layer of stones is almost covered.
Four: Check for leaks.
Six: Use plastic pellets when necessary to increase the volume andcushion the stones.
Seven: Clean the barrel, stones and plastic pellets thoroughly in between steps.
