Complete metal polishing rotary tumbler kit. You'll love this complete barrelling kit if you want a fast way to polish up metal. The 3lb Beach Metal Barreling Machine is ideal for jewellery makers.

It’s perfect for sterling silver, copper, bronze, and metal clay like Art Clay, PMC, and Copper and Bronze Clay. This tumbler is British made and consists of a high-quality motor and a 3lb plastic barrel with vanes. The vanes help speed up metal polishing. 

The 3lb motor and barrel makes it great for a larger studio, where you want to polish up a fair amount of work. If you want to polish very large amounts of work, or heavier loads, we recommend you choose the 5lb Barrelling Machine instead.

Tumble polishing is the the easiest way to give your silver pieces a beautiful shine. Just put your silver in the tumbler together with water and steel shot, and leave for anything between 1-6 hours, and they'll come out lovely and shiny. This complete kit (suitable for tumbling silver or metal) comes with the steel shot and barrelling compound which you need to polish metal. Everything you need to tumble polish, together in one complete kit!

Kit includes: 

  • 3lb plastic vaned barrel
  • Tumbler base with motor
  • Standard steel shot mixed shapes - 500g (use the options to upgrade to other types of shot, like Stainless Steel or Premium Pin Free)
  • BarrelBrite polishing compound - 250g

How to use your tumbler kit day-to-day: 

  1. Open the barrel (when using plastic barrels, you must put the lid-end in HOT water first to soften it).
  2. Carefully drain out most of the old water which your shot has been sitting in.
  3. Fill with a little water from the tap, swirl the shot around to give it a rinse and pour out most of the water (if it looks very grey and scummy; repeat this step until more or less clear).
  4. Fill to slightly less than half full with clean water.
  5. Add about 0.5 teaspoon of barrelling compound. Exactly how much to add depends on size of barrel, amount of water, and your water quality. If the barrel is full of foam when you open it to check after an hour, you've added too much.
  6. Add the metal to be polished
  7. Replace the lid (if using the plastic barrel, don't forget to put the lid in hot water before replacing it)
  8. Tumble for an hour or more. Whilst you're getting to know your tumbler, check your pieces every hour to see when you're happy with the finish (don't forget to warm up the lid!). When happy with the finish, take out your sparkly pieces.
  9. When finished, make sure the shot is always completely covered by water; add water (and about 0.5 teaspoon of compound) until it covers the shot, this helps to protect the shot and keep it clean and rust free. If the water looks very dirty and messy you might want to replace some with fresh water.

The vanes in the barrel helps to move your pieces around, so they polish faster. We used to use this size barrel in our metal clay classes, which were up to 10-12 students who each made between 1-3 items (usually earrings and pendants), and the size was perfect.

Alternatively, you can fit 2 of the smaller 1.5lb barrels on this tumbler motor body, in case you want to replace the 3lb barrel. We offer extra barrels in plastic or rubber; plastic is much easier to keep clean, whilst rubber is easier to open and close and are quieter - so you can mix 'n' match them as you like. 

A little note on polishing - this tumbler is designed to polish or burnish your pieces. If you use it with steel shot and water it is not an abrasive - so it will not remove scratches. If you have any scratches you need to put in a little work and remove these by hand before you tumble. Tumbling for a long time might round off and smooth out the scratches slightly, but it will not remove them.

A couple of notes on maintenance:

  • NEVER remove or replace the plastic barrel lid without warming it up first. Set it in a bowl of hot water for 30-50 seconds before using.  If you don't warm it up, it will eventually crack. 
  • Remember to "burp" the lid before tumbling - if you don't know what this is, have a look at the video above.
  • Every week, unplug the tumbler and put a drop of oil on the steel shaft of the roller where they pass through the bearing blocks. This is a great oil for that.
  • Every month, put a drop of oil on the motor shaft, where it protrudes through the side of the machine (use engine grade oil for this). 
  • Always keep your shot covered by water. Rusty shot will damage your work and needs to be disposed of.

Size of each barrel: 14cm L x 10.3cm inner diameter, 12cm outer diameter
