    Hello All: When a jeweller charges thirty dollars for a simple
    downsizing, he is probably charging three hundred dollars an hour ! 

    I was just wondering if anyone out there was that fast (10 rings
    down in 1 hour) on a day to day basis or even ever once? I have sized
    "new sale" rings in 10 to 15 minutes depending on how many sizes up
    or down, types of stones and settings but 6 minutes seems not likely
    to me. 

    It takes you some time to go thru all those job envelopes and
    document which rings go with which job and that has to count towards
    the time. Lets say that the 10 rings have already been in your
    ultrasonic and are clean and ready to go. 

    Go. First you put the ring on your mandrel and determine how many
    sizes it goes down. You mark and cut the piece out. You close the
    shank. You steam it off and dip it in your borax and alcohol and set
    it up on your third arm. You cut your solder and flux the joint. You
    light your torch and flow your solder. You let it cool (or quench it
    right away if there are no stones) and into the pickle and then the
    ultrasonic for a few seconds. You steam it off and back to the bench.
    You smooth the inside of the solder joint and then put it on the
    mandrel and hammer it round. You finish the inside alittle and then
    file the excess solder from the outside. You polish with a flex shaft
    wheel until smooth and then up to the buffing machine. You polish the
    whole ring and then into the ultrasonic for a few seconds and then
    you steam it off and inspect it. Hopefully none of the stones have
    fallen out or are loosened and no other problems are found. So, what
    say you out there. Is anyone out there sizing an average of 10 rings
    an hour?  How many should an expert bench repair person be able to
    size in an hour? Michael R. Mathews Sr.   Victoria,Texas    JACMBJ
