The Kitiki Professional Lapidary Kit For Glass, Lapidary, Metals, Minerals, Rocks, And Stones.

The Professional Tumbler Kit is generally used for smoothing and polishing glass, metal parts, minerals, rocks, and stones, although it has other applicatons. It's ideal for putting a matte or gloss finish on beach glass, garden discoveries, and small pebbles.

The kit comprises a motor base, a 950cc diameter rubber drum, a three-grit pack with 400gms of 80 grit, 400gms of 220 grit, and 340gms of 400 grit, 200 gms of zinc oxide polish, and 250gm of plastic pellets to distribute the polish.

Tumblers and polishers can be used to refine, matte, or gloss the surface on brass, bronze, cartridge shells, castings, coins, copper, fashion accessories, fingerprint keepsakes, glass, gold, gun components, jewellery, keys, metals, minerals, model parts, rocks, shells, silver, small treasures, and stones. And there are diverse archeological, engineering, geological, hobby, and industrial applications.

Prices here are transparent: the kit prices include a UK-EU voltage and CE-marked motor base, a rotating drum, abrasive or polishing media, comprehensive instructions, UK VAT, and continuing free support from a top-tier international distributor. So you can start work straight away.

You don't have to buy a complete kit. All the components for all the kits are available separately, so you can mix-and-match the combination you need. To learn more about the separate parts, use the separate parts link.

The Kitiki Professional Tumbler Kit For Glass, Lapidary, Metals, Minerals, Rocks, And Stones.

The kit comprises a CE Marked motor base, a 950cc 135mm x 113mm diameter rubber drum, and a three-grit pack with 400gms of 80 grit, 400gms of 220 grit, and 340gms of 400 grit, 200 gms of zinc oxide polish, and 250gm of plastic pellets to distribute the polish. The kit uses the Kimber Allen Evans Junior motor base.

The motor is rated at 230V-240V 40W, so can use a regular mains socket. It's fully-enclosed inside a vented aluminium case rather than, as with some tumblers, exposed at one end: so it's less prone to damage and damp, and takes up less space.

Including the barrel, it measures 200mm x 130mm x 200mm high, weighs about 2kg, and comes with a 1.8 metre cable ending in a UK 3-pin plug. Plastic protectors stop the tumbler marking your work-top, or slowly creeping and falling off.

The barrel revolves on two plastic rollers, one of which is turned by the motor. There are two roller-ball barrel end-stops and a nylon-reinforced toothed drive belt which can be adjusted for tension, although it's intended to be loose.

The 950cc drum is often called a full-size or 3.0lb drum. However, as it holds 950cc of water, about 950gm, it's really a 2.09lb drum. So, if you see it described elsewhere as having an actual capacity of 3.0lb, it doesn't.

As you can see in the photo, the 950cc rubber drum uses the full width of the tumbler body, but you can use two smaller 510cc drums at the same time. For some types of work there's an alternative 1000cc pro rubber drum which has two vanes inside to help the mixing and tumbling action.

The grits are silicon carbide: an angular, hard, sharp, material which fractures into smaller angular particles, making it an effective abrasive. Generally, 80 grit is classed as medium, 220 as fine, and 400 as very fine. They come in plastic screw-top pots: not plastic bags, and not pots that can't be closed once the seal has been broken.
The final phase for polishing glass and stones uses a very fine zinc oxide paste mixed with small plastic pellets to help distribute it and stop it sticking together in lumps.

The Kitiki Professional Tumbler Kit For Jewellery, Silver, Gold, Art Clay, PMC, And Metals.

If you've already bought this tumbler for glass, minerals, rocks, and stones, but now want to try jewellery, metals, and silver, you'll need 500gms of mixed-shape, rust-resistant, stainless-steel shot and 225cc of special cleaner and corrosion inhibitor.

However, grits and polish are a bit like sandy toothpaste, and cleaning out a drum completely, storing the grit, and swapping back to shot is messy and tedious. And I wouldn't recommend using the same single drum for grits and shot as one stray grit particle in the shot will scratch your work.

You could use two barrels: one for grits and one for shot, marked so that you don't mix them up. But, budget constraints aside, it's much better to use four drums for the three grit grades and the polish, and one drum one for the shot. It makes cleaning and storing easier, especially as the three grits look similar and the polish must be kept grit-free.

Finally, remember that, as an alternative to the one medium barrel, the motor base can hold two smaller rubber barrels: you can use both with shot, both with grits, or one with shot and one with grit, at the same time.
