    Brian this is like polishing a small section of a beat up '79 Pacer.
    Once you start, the rest looks like junk. 

    The problem with the flexshaft is you cannot get the same angles,
    etc so you are basically just acting like a dentist. Polishing
    requires a metal or ceramic lap. You can have mylar sheets such as
    spectralaps etc on a master lap but you're going to have a lot of
    trouble if you try to use a buff or something with diamond on it
    since it is so soft (not to mention diamond paste flying everywhere)
    it will be hard to put any pressure to remove scratches. 

    What kind of stone are you trying to clean up? How deep are the
    scratches? I recently looked at some stones from a major
    jewelery/gem mfg and they looked like they were final 'polished' on
    a 3000 mesh lap. Not a polish in my book but it must be acceptable
    somewhere since people are buying the stones. You're not going to be
    able to do much with a stone like that with a flexshaft without
    messing it up. 

Just my.02, good luck!
