When selecting a coin, note the following parameters:
security;

For example the US Dollar, and bronze alloy thereof do well rings with larger diameter coins some EU made of bronze and alloys of various sizes.
A ring of coins with his own hands: the master class
need:
coin;
vise;
power with attachments for grinding and polishing;
drill;
steel spoon;
metal platform that serves as the anvil;
fine-grained sandpaper.
1.Coin put on the "anvil" edge, apply to it the convex part of spoon and small impacts are passed evenly across the edge of the coin. Periodically check the shape of the workpiece.
2.Stop when the edge of the coin will be necessary for our ring width.
3.Using a nail or pointed object, we envisage the center.
4.Drilled with a drill in the center of the coin is a small hole, stop the drill as soon as it passes through the end of the coin. The drill is jammed in the metal, which will allow us to meet the next stage. Be careful, because the ring is heated during drilling and can be burned.
5.Take a coarse sandpaper, and include a drill to drill on the coin cool, treat the outer ring of the preform. Then take a fine sandpaper and repeat the process.
6.We perform final processing of the outer surface. To do this, take a cloth to put the abrasive composition and polish their surface. For gloss repeat such processing repeatedly.
7.Hold the coin in a vice, using the lining in the form of cardboard or paper to protect it from scratches and dents.
8.Increase the hole in the coin using a drill or other device. This is the most difficult and laborious phase of work, as it is likely to spoil the coin. Do whatever is necessary to gently, slowly, periodically check the attachment of the coin.
9.Using the tool with the grinding roller, flatten the inside of the ring. After this step, the edge of the product will be quite sharp.
10.Loop through a file on the edges of the product from all sides at an angle of 45 degrees, until they become more rounded.
11.A nozzle with a small polishing amount of the abrasive grind the inner surface of the product, removing any remaining roughness.
