It is most important to keep your various types of metals separated with additional drums. For example using silver in a drum you usually use for gold will cause your metal to look yellowish. Please note for ease of use we have approximately calculated media, solution, and component capacity in both stages for all our range of Barrelling Machines.

Tips: Please note platinum is a metal you can use with the first stage of the barrelling process but hand finishing will achieve the best results replacing the second stage process. Cousins supply a large range of mops, compositions and abrasives for the ultimate high mirror finish.

When polishing platinum casts or handmade items use at least three grades of abrasive paper to level the metal and then follow the barrelling stages above. Remember platinum is a hard metal so ideally it needs these three stages of polishing to attain an expert finish.

If you plate over an item you have barrelled the item will not give as high a finish compared to hand finishing; the piece maybe pitted or marks. Please remember barrelling is a burnishing process, it does not remove the surface area like a mop finish does.

All our barrelling machines can be used with steel, plastic or ceramic media. Please be aware however that harder media such as ceramic and steel will wear the barrel quicker than the plastic media

Stage 1

Deburring – produces a matt surface, removes marks, scratches and surface defects and can also be used to remove sharp edges.

• Every one litre in your barrel body will take 250g of green cones (B4903);

• Use 5g of PB Cutting Powder (C4904) per litre of water. For added potency add five more grams of PB cutting powder to ensure more abrasive removal of metal;

• Use 5g of barrelling powder to one litre of water (C4365);

• The efficiency of the barrel is dependent on the ratio of volume of work to the weight

Stage 2 Polishing – produces a semi bright finish on many metals reduces work on polishing wheels and does not damage delicate items. In barrelling, the pieces and polishing media mix as the barrel drum rotates; the de burring or polishing action is due to the surfaces of the article and media sliding over each other under the pressure exerted by the mass of the media. Modern barrelling processes involve the use of barrelling compound (C4365) which is mixed with water together with media. It prevents the media from glazing and also keeps the components and tumbling media in good condition.

Barrelling Media:

For effective barrel burnishing it is essential that suitable media be used and that these be maintained in good condition. For the majority of barrel
