    Having done this several times, the thickness and width of the
    hacksaw blade, the hacksaw frame having posts that the blade connect
    to makes this pretty near impossible to happen. You are using the
    polishing motor like a lathe. The shaft of the motor is soft steel.
    It takes very little pressure for the blade to cut, so you are not
    forcing the blade. When you are holding the saw frame, your wrist is
    on the other side of the frame away from the spindle, so a sleeve
    would be 4-6 inches away from the spindle. 

    From my experience, considering that it takes about two minutes to
    cut both spindles this way, 

    I do not believe it was risky, or that I was unwise. Having said all
    this, if it seems dangerous to you, do not attempt it.
