Shouldn't the left hand threads be on the right side, so they'd tend to
tighen upon themselves with forward motion? I'm thinking if the nut was
loose, and the wheel suddenly started spinning forward, a right hand thread
on the right side would tend to spin off, correct? Or is this where that
complicated explanation comes into play? ;o)
