The Kitiki Rotary Kit 2 is a home-use rotary tumbler, ideal for buried treasures, coins, glass, metals, minerals, rocks, shells, and stones. It consists of an electric motor base, a 700gm plastic barrel, 200gms of 80 grit, 200gms of 220 grit, 150gms of 400 grit, 150 gms of cerium oxide polish, and one pack of plastic pellets.

The CE-marked fully-enclosed motor is rated at 230V 15W, so can use a regular mains socket. Since the tumbler uses less power than a fridge bulb, the cost of using it is less than a penny a day. It measures 143mm x 122mm x 205mm, weighs less than 1kg, and comes with a 1.8 metre cable ending in a UK plug.

The plastic barrel has a push-fit lid, and revolves on two rubber rollers with the roller end-stops keeping it on the rollers. The drive belt is soft neoprene.

As you can see in the photo, a 700gm plastic drum uses the full width of the tumbler body, so you can't use a large drum or two smaller drums. The 700gm drum is often called a half-size or 1.5lb drum.

If you want a larger tumbler, look at Rotary Kit 4. If you want to tumble metals, you need a shot-tumbler: so look at Rotary Kit 1 or the larger Rotary Kit 3.

Kitiki Rotary Tumbler Kit 2.

Rotary Kit 2 is a small, inexpensive, home-use, glass and stone tumbler. However, unless you're economising, you should upgrade the barrel. Here's why:

A plastic drum is quite noisy: important if you want to work in the same room. When fitting the lid, it needs to stand in hot water to make it easier to push on. To free the lid, the whole drum needs to stand in hot water. There's a slight risk that, as you prise the lid off, you'll spill your work, shot or grit, and soapy water.

Rubber drums have a different lid: at one end there's an inner metal lid, a rubber sealing ring, a metal outer lid, and a screw-on retainer. They're easier and simpler to work with than plastic drums, and don't leak.

It's important to understand that coarse grit is like fine sand, medium is like caster suger, and fine is like flour. Although it sounds straightforward to empty each one out and fill the drum with the next, it's actually a bit messy especially with the fine.

Unless you're on an economy budget, four drums make cleaning and storing easier, especially as the polish must be kept grit-free. Although, it makes more sense to use a larger tumbler such as the one in Kit 4 so that you can use two drums, with different abrasives, at the same time.

If you've already bought Kit 2, but now want to tumble jewellery and metals, you'll need 1000gms of shot and 175gms of barrelling compound. You can buy these now, or later, in the on-line shop.

Grit is the generic name for the abrasive particles used to grind and polish. Generally, it's silicon carbide: a hard, sharp, angular material which gradually fractures into smaller angular particles, making it an effective abrasive. However, unlike shot, it does need replacing eventually.

80 grit is classed as medium, 220 as fine, and 400 as very fine. However, you'll soon learn which grits to use, and for how long, for different materials, shapes, and finishes.

If you're intending to tumble a lot of glass and stones, four drums make cleaning and storing easier, especially as the three grits look similar and the polish must be kept grit-free. However, it makes more sense to use a larger tumbler so that you can use two drums, with different abrasives, at the same time.

If you want to do shot-tumbling and grit-tumbling, you should use two barrels: marked so that you don't mixed them up. One stray grit particle caught in the drum will scratch your shot-tumbled work: the scratches are quite hard to remove.

A silicon lubricant is used during the manufacture of rubber drums. Before use, clean the drum with a scouring pad and some washing-up liquid.
