[pianotech] center pin function

[Keith McGavern]

Dear persons,

I found this an interesting question as well as a response.

My understanding and practice to date dictates that when the center  
pin is pinned properly, the center pin does not move or rotate at all.

I am fairly certain that is what Al meant to say, but semantics may  
have got in the way.
