Hi Andrew

    I have alwas found that it is difficult at the best of times to get
    a very nice detailed wax of a class style ring from a rubber mold.
    You can get duplication, but it is not really bright and sharp. What
    I had done to get the best wax, was use a small drill bit, and drill
    form inside to outside of the mold at all the high points in the
    rubber..i.e. letter tops and detail spots etc. It helped alot to
    bring the letters out but did increase the wax cleanup a bit. It
    increased the reproduction from bad to marginally acceptable. Nothing
    close to the sharpness you would get form a machine milled wax or
    plastic injected model. 

    If you are thinking about getting in injector, be sure to get a good
    one that will give you quality injections and last forever. I have a
    spare used Kerr Injectomatic kicking around my shop I would be
    willing to part with. If you ae interested e-mail me off list. 

    Good Luck 

Dave
