    It is very risky trying to saw a spindle while it is moving and
    should not be attempted. If the blade sticks in the cut while the
    spindle is turning, it can break and fire the sharp broken end into
    your stomach!!!, not to mention the possibility of getting a sleeve
    snagged by the rotating shaft and mangling your hand... - not a wise
    thing to do. Always cut a spindle while it is stationary - if you
    are fitting a push-on taper sleeve, it doesn't matter if the end
    isn't cut exactly at a right angle. You will also probably find it
    easier to cut if you strap the spindle to the motor casing with
    'gaffer tape' (duct tape) to prevent the spindle turning while you
    are cutting.
