Isn't Nanopin a small town on Cape Cod?

Terrific! Another field of study. But do you actually think that the cap 
itself is "sliding" up and down the pin? You measured, as I recall 80 
thousandths difference or in the vicinity; couldn't this as well be wood 
fiber expansion instead of, well wait a minute, maybe this six of one and 
half a dozen of the other. I just have a hard time picturing the CAP rising 
and subsiding like that. Are we talking about different coefficients of 
expansion between same wood/different grain orientation? But, yes, I have 
noticed the notching on the pin and have attributed it more to string 
movement than pin movement or cap movement. HMMMM. Truly nanopinology.
