What do we need for this:
-Coin (exactly the diameter that you need, for example, if you take a diameter of 15 mm, then your ring will turn out 15 mm, maybe a little less, but no more, otherwise the ring will burst!
- The crossbar (that on which we will put on a coin), it is possible to replace with any steel cone of a suitable form and size
- Drill, punching or other device for making a hole in a coin
Hammer, preferably with plastic heels (to save the coin pattern)
- Burner, water
-Polishing Tools (Dremel)
Step 1
We make a hole in the coin, the author used cutting down for this. (And you can drill.) Here you need to think about what pattern or inscription on the ring you want to get:
Step 2
We can greatly facilitate our work by making the coin softer! But how to do that? First you need to find out what the coin is made of. We take a magnet and check: if it is magnetized, then it is steel, if not, then it is non-ferrous metals.
Now if that steel-Warm up to red and cool slowly, removing a millimeter from the burner!
If this non-ferrous metal, then we “anneal” the coin: heat the coin to a red-orange hue and sharply cool in cold water.
You can also heat the coin during manufacture
Step 3
And now the most interesting! We put our coin so far on the crossbar and very neatly, but confidently tap the plastic mallet!
Step 4
Many coins have a thickening on the edge, this is the side of the coin. To remove it, the author uses a dremel with a large skin
Total:
We got:
But you may not succeed the first time:
