Hello Freak Style,

    I must share my personal experience using a grinder as a polisher. 
    Long story short, I realized my folly when I began coughing up dark
    mucus after an hour of polishing on my grinder. Not to mention the
    lovely black dust that was coating everything. The grinder has no
    powered exhaust system with a filter to collect the fine particles
    generated during polishing. If you are in an enclosure, you'll be
    breathing those airborn particles. 

    If you insist on polishing this way, do it outside and wear a
    close-fitting dust mask and goggles. Save your money to buy a
    ventilation/filtering system ASAP. Your lungs will thank you. The
    other part of this story is that a grinder motor doesn't rotate as
    fast as a polisher and tends to lug down in use. That means more
    time to achieve a decent polish - more exposure to particulates in
    the air. 

    Heck, buy an inexpensive vibratory tumbler from a re-loading
    supplier and get Judy Hoch's book on tumbling techniques
    http://www.marstal.com/basic/thebook.htm. The tumbler and book are
    an excellent investment that can help you do more with less and
    reduce your use of that polisher! 

    We want you to grow old in good health.

    Judy in Kansas, 
    who is hoping the folks in Louisiana and Mississippi are OK and
    recovering quickly after the hurricane.
