Here is the ring after firing & polishing. I'm looking for more information on using the Japanese made Ring Maker. It works well to make a seamless ring. I did use the 12mm thick attachment and cut the ring down to the desired thickness. P.S. Rings are very hard to photograph--I'm still working on it! This is the best of the first attempt, the hard part was getting the ring to stand. I ended up using a very small piece of putty.
