NSI Rock Tumbler Classic

Model: 635   |    Mpn: 635   |    Ean: 0042409263549   |    PartNumber: 635   |   Asin: B00000ISUU

Change rough stones into beautiful, high luster gemstones with this U.L. listed heavy duty Rock Tumbler. Includes Rock Tumbler Machine, Rough Semi Precious Stones, grit, Polish, Jewelry settings, and detailed instructions.

It may be a grind to wait nearly 30 days to create polished rock jewelry with the Rolling Stones Rock Tumbler. But, as the makers write, "you are grinding in days what it takes nature thousands of years to do in a stream, river, or ocean." So, find a clean, remote area with a properly wired outlet where the constant tumbling won't disturb others (and where curious little hands won't wreak havoc), and start rolling. The first step involves assembling and lubricating the tumbler itself. Once the two-cup, plastic barrel rolls easily atop its 10-inch-long and 6-inch-high plastic base, it's time to open the small bag of gritty stones that comes with the kit. Constant maintenance and much patience will reward the owner with shiny stones in about one month. A small sampling of jewelry settings and findings is provided, along with order forms for gold-tinted accessories. -- Liane Thomas

Features

  • Change rough stones into beautiful, high luster gemstones
  • UL listed heavy duty rock tumbler
  • Includes: Rock Tumbler machine, rough semi precious stones, grit, polish, jewelry settings, and glue

Polly Plastics Ceramic Rock Tumbling Small Media. 1.5 Lbs Rock Tumbler Filler Small Cylinders in Heavy Duty Resealable Bag

Model: 683405246992   |    Mpn: 683405246992   |    Ean: 0683405246992   |    PartNumber: 683405246992   |   Asin: B075MWVBQ1

Our non-abrasive porcelain ceramic tumbling media is perfect for protecting and cushioning fragile stones while tumbling. Also, use to fill your barrel to the recommended level, carry grit & polish, improve tumbling action and quiet the tumbling process. Recommended over plastic filler media for vibratory tumblers. Since porcelain ceramic rinses clean of grit, you can use the same batch of ceramic through all the stages. Just rinse off between stages, along with the rocks. This large 1.5 lb. bag allows plenty of cylinders for multiple tumbler loads. Do not use fresh cylinders when polish tumbling in Stages 3 and 4. Run the cylinders in the tumbler with water for a few days to smooth off the edges. Preferably, use the fresh cylinders as fill for Stages 1 & 2 so they will have lost their edges by Stage 3. Most tumbling media comes packaged in cheap plastic bags that easily tear and spill. We use a thick, re-sealable bag that won't break and cause a mess. If you have extra cylinders - just zip up the bag and use it for a later project. Polly Plastics sells premium porcelain ceramic. 100% satisfaction guaranteed. WARNING: Choking Hazard-small parts. Not for children under 3 years.

Features

  • 1.5 Lbs. Non-Abrasive, Porcelain Ceramic Small Tumbling Media. 3/16" dia. X 3/8" long, 22 degree angle cut cylinders.
  • Perfect for protecting stones or filling while rock tumbling. Cushions, quiets and improves tumbling action. Recommended over plastic media for vibratory tumblers.
  • No need to keep separate for each stage - rinse and use the same batch through all the tumbling stages. Non-toxic, non-static and non-residue pellets are dryable and easy to reuse.
  • Packaged in durable, re-closable seal bags to prevent messy spills and to safely store unused pellets for later.
  • PREMIUM porcelain ceramic

Our clear plastic pellets are perfect for protecting and cushioning fragile stones while tumbling. Also, use to fill your barrel to the recommended level, improve tumbling action and quiet the tumbling process.

Most pellets come packaged in cheap plastic bags that easily tear and spill. We use a thick, re-sealable bag that won't break and cause a mess. If you have extra pellets - just zip up the bag and use it for a later project.

Leegol Hobby Rock Tumbler Machine - Single Barrel 3LBs Rotary Rock Polisher (Single)

 Ean: 6743476902969   |    PartNumber: PG-LG-1-2   |   Asin: B07CBTZWQP

Specifications:

Motor: 120V/60Hz Barrel Capacity: 3LBs
Material: sheet metal ,rubber
Five more v-belt
Easy-to-follow rock tumbling instructions
Noise reducing leak-proof barrel with aluminum lid
High-quality tumbling machine with powerful motor that will last for years

How a Rock Tumbler Works:

The motion in the barrel of the Tumbler simulates the natural action of flowing water or ocean waves. Beaches and riverbeds contain rocks and pebbles smoothed by water and the abrasive sand it carries. As rocks grind upon one another with constant water and sand in the mix, they begin to round and smooth. Although this is a constant process, it does not however, naturally polish the rocks.

The Tumbler uses an abrasive media instead of sand. It is graded by grain size, from fine powder sized grains, up to large sized grains. By changing (usually by weekly intervals) the grain size, rotating from coarse, medium, to fine, the rock or gemstone is smoothed much more quickly than the natural process.

To polish using a Tumbler, add a metallic oxide compound (not included). The complete process for a gemstone or rock to go from rough to smooth, polished finish, usually takes 4-6 weeks.

Great way to start a rock collection:

Rock tumbling is a fun activity for children of all ages and promotes an interest in geology and science. Introduce your kid to science the fun way.
