Hi all,
         My two bits on this hole thing.  Maybe some one should come up
with a differential equation,just to see how this hole behaves. Since the
rate of expansion is different for the cross grain than end grain, dy/dt,
we could keep this hole thing going for years, further more are we talking
about 10 growth rings per inch or 15, as this also becomes a variable.
  Now perhaps we need to integrate this hole just to predict the actual
shape that it is going to contort into, but then is the key white pine or
sugar pine? darn another variable.
  The old timers did'nt have such a bad method by using a dab of glue and
brown paper. If you use white glue it does not set like cement and is'nt
noisy.
  Trust my dear friend Don to start the ball rolling on this one.
