In the beginning I was so ambitious that I decided to make a set of zodiac coins. It is one set that I saw in MET and got quite into it.
But I found it quite hard, the pattern is too small, I have to use 1/64 bit and it took hours for the aluminum to finish. So, I changed my idea and tried if I could fit two piece together and used a new material - aluminum.
I set an offset of 0.1mm to the inner part and outer. It looks a little loose, there's very obvious gap between them.
This is the result after polish.
And the final piece.
