Thumler's UV Mini Bowl
Thumler's UV Mini Bowl Vibratory Rock Tumbler
This small capacity vibratory tumbler is a new addition to the Thumler's Ultra-Vibe vibratory tumbler product line. The UV Mini Bowl will process approximately 4 pounds of material, including both rocks and media, at a time. This smaller capacity is great for people who prefer to run small batches or for experimenting to get the best results on a certain type of material.
If you currently run a small capacity rotary tumbler this machine will make a great addition to your tumbling equipment. You can run one or two batches through coarse grit in your rotary tumbler and then finish them more quickly and using less supplies with this UV Mini Bowl vibratory tumbler.
We think it is the perfect companion for a Thumler's A-R2 rotary tumbler. After running the two 3-pound barrels of material through coarse grit you should have about 3 pounds of material ready for medium grit. Place that rounded material into the UV Mini Bowl bowl and add ceramic media to get the UV Mini Bowl bowl up to operating capacity. Plastic pellets are not recommended for use in vibratory tumblers.
Maximum Size of Rough
The bowl on this UV Mini Bowl vibratory tumbler can handle rough up to about 1 3/4 inches in diameter. If the piece of rough is more of an egg shape the long axis can be longer than 1 3/4 inches but the narrow part of the stone must be 1 3/4 inches or less. For best results we suggest not putting more than 2 or 3 pieces of that size in the bowl at a time. Fill the rest of the bowl with smaller rough material ranging in size from 3/8 inch up to about 1 inch or a use ceramic media to get the bowl to operating capacity.
UV Mini Bowl Operation Basics
1) Load the bowl with approximately 4 pounds of material. The 4 pounds includes the weight of the rough and media used.
2) Add grit. We use one level tablespoon of grit or polish for every two pounds of material.
3) Add water. A very important step. There is not a specific amount of water that you will add every time. The key is to add just enough water to get the grit to stick to the material. Here is how we do it... Turn the tumbler on before adding any water. Once it is running add a little water at a time. We use a taplespoon to ensure we don't hadd to much. If you add to much water it will pool at the bottom of the bowl rinsing the grit off the material. If you do not have enough water the grit cannot stick to the material.
