    Thanks Dennis. you bring up some interesting points. With all the
    technical points that posters have made this is a great learning
    experience. 

    Switching to a flat lap seems odd; why not just continue with 8"
    wheels. That way one has full contact with the wheel. I have a 6"
    flat lap as well as an 8" flat lap. The speed varies in proportion
    to the distance from the spindle. It's easy to catch an edge. 

    Somewhere in the dim mists of the past I remember someone suggesting
    using a length of bamboo to cradle the material being cut. Perhaps a
    60 section would be cut out for the opening to reach the cutting
    surface. 

    Thanks for taking the time to outline your method.
