 as a first course of action to drive all the pins a smidgen deeper.
 That worked pretty well, but I got the distinct impression as I was
 going along that the tuning pins were hitting bottom in the holes.  A
 pretty good whack didn't noticeably move some of them.
 
 Is this possible?  Has anyone had opportunity to notice if a factory has
 ever drilled the pinblock on a vertical too shallow?

I don't know for a fact that holes were drilled to a certain point, but I 
have experienced the same thing. So there must be something to your 
observation.
