Kitiki Rotary Tumbler Kit 4

The Kitiki Rotary Tumbler Kit 4 is a craft, engineering, studio, frequent-use kit, ideal for buried treasures, coins, glass, metals, minerals, rocks, shells, and stones. It consists of an electric motor base, a 950gm rubber 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 motor base is longer than that in Kit 1 and can hold two 510gm rubber drums, but not two 700gm plastic drums.

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 about a penny a day. It measures 195mm x 105mm x 200mm, weighs about 2kg, and comes with a 1.8 metre cable ending in a UK plug.

The rubber barrel revolves quietly, the drum lid has a leak-proof easy-to-fit lid with a seal and a retaining collar, and the rubber rollers and rollerball end-stops keep the drum in the correct position. The drive belt is toothed and nylon reinforced, so it won't slip or wear out quickly.

As you can see in the photo, a 950gm drum uses the full width of the tumbler body, although you could use two 510gm drums if some work needs a long tumbling time and other pieces just need a quick freshening up. The 950gm is often called a full-size or 3lb drum, and the 510gm a half-size or 1.5lb drum.

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.

To make sure that the instructions are always up-to-date, we don't put anything in the box. The latest version is free, and can be printed here, using the instructions link below the menu bar near the top of the page.

Plastic drum lids need to stand in hot water to make them easier to push on. To free the lids, the whole drum needs to stand in hot water. There's a slight risk that, as you pull the lid off, you'll spill your work, shot or grit, and soapy water.

Rubber drums use a different lid mechanism: at one end there's an inner metal lid, a rubber sealing ring, a metal outer lid, and a retaining threaded collar. They're easier to work with than plastic drums, and much quieter in use: important if you work in the same room.

The stainless steel shot, included in some of the rotary tumbler kits, is actually a mix of shapes, such as pins, planetoids, and spheres, designed to deal with the range of contours on jewellery.

Although the shot is 100% stainless steel, always leave it immersed in the tumbler mix of water and cleaner, or rinse it and dry it carefully. If you need to replace the shot, don't economise and buy plain or mixed steel: it'll soon rust, make a mess, and ruin your work.

Grit is the generic name for the abrasive particles used to grind and polish. Generally, it's graded silicon carbide: an angular, hard, sharp, material which fractures into smaller angular particles, making it an effective abrasive.

Grit sizes are confusing, for example: 400 grit particles are not twice the size or half the size of 200 grit particles. You'll soon learn which grit to use for different materials, shapes, and finishes.

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.
