[TowerTalk] Metal Thermal Rate of Expansion

[David Gilbert]

I'm not sure that percentage of expansion is the relevant consideration 
here.  I would think that the gap between the cylinders (i.e., portion 
of the diameter) is the important part, and since the expansion occurs 
in the circumference the gap changes by a factor of pi less.

Even less reason to be concerned, I think.
