***Frequently Asked Questions***
-1. Why is there black powder/dust on my floor?
Dont worry, its normal, the barrel is made of rubber and is strong enough. Due to the friction between the machine and the barrel, some black dust may appear in the first few days of tumbling. Before tumbling, please gently push the barrel toward the belt to ensure that the barrel is close to the edge of the machine to avoid black dust. If it breaks, well give you a new barrel, but were sure it wont.
-2. Can I put collected stones or even other items like glass or coins into the rock barrel?
We recommend that you choose a stone hardness between 6-8(Read more about the hardness of a stone on page 14 of the Learning Guide). If you want to tumble other things, you may need to learn and master some skills on how to polish the same thing. The steps may not be the same as tumbling a stone. Lets start practicing and believe that you can practice makes perfect.
-3. Why does the barrel not turn?
Check that the barrel is not underloaded or overloaded. Thoroughly dry the drum and bucket, making sure there is no oil or water on the bucket. If it looks shiny, dab it with sandpaper.
-4. Why is the final polished gemstone less shiny?
As the moisture evaporates from the surface of the final polished gem, the gems appearance will reveal its true nature. You can apply a layer of mineral oil to the top of the gemstone to maintain its luster.
