Some countries have strict laws on the destruction or change of issued currency, but similarly, some countries do not. Citizens in the latter category may like to build a small box similar to [elier Olivos] made of a large coin.
The compass is first used to draw a line on the circumference of the coin, and then cut it in half with a friction saw. Once the two halves of the coin have been ground flat, they should be heated and quenched so that they can be more easily struck into a slightly domed shape. Then make metal rings and add them to each half to make the small box have a certain depth.
Then carefully make the hinge and fix it on the edges of the two halves of the coin to make the appearance of the closed coin almost seamless. The small latch installed inside helps to keep the small box closed. The last step is to tie a ring on the necklace for the wearer and polish the inside of the small box to a specular luster.
[elier] makes the build look simple with his amazing two handed skills and some esoteric tools. It’s very relaxing to shoot a master’s video at work. We’ve seen some good examples recently. Video after break.
