Sorry for the delayed response!  Having fun trying to
figure out this problem. :-)

Nice to know.  Thanks!!!

Two blunders "I" did.
  1) Tried to turn a dowel.  Green wood weighs about
     twice what kiln dried wood does and the added
     moisture content reduces the heat caused by
     friction.
  2) Too many loops wrapped around the piece being 
     turned.  This subjected the cord to continual
     heat weakening the cord.
