As I continue to stumble blindly into the darkness I'm going to try to make a mold of the good parts of the ring. I don't know if this will work but I'm going to try. getting silicone any where near anything that needs painted freaks me out. I wrapped it tightly in electrical tape with some overlap to keep the silicon from touching it. This will make my mold a little bigger with the ridge for reference point and give me something to sand. I hope to get something close to the right shape to work with. I started with 2 1" strips of 1/4" plywood and put packing tape on the outside and siliconed the joint so I can cut the mold open. I then put a dado almost all the way through every inch. Mostly it's the packing tape holding it together. I used the thick super glue to build the mold and siliconed the joints after drying. I made tops for them to glue on when filled. Keep in mind I don't have a clue what I'm doing and have never made a mold before.
