soundboard

[Kurt Eichenbach]

Sure, sounboards loose their crown as they get old, nobody can argue 
with that.  But the whole soundboard fluctuates in its old age more 
than a new board.  Wood shrinks and grows more in its old age.  Why 
were wooden action parts replaced with plastic parts if wood got more 
stable as it aged?

But I'm glad I asked this question and I'm glad to get answers.  With 
regards to the tuning block, wow, you are so right.  I need to get my 
tools and go hammer in some pins on an old vertical that I can think 
of.  It's been a few years since I did anything but tuning so now my 
cortex has been filled with other data and I need to retrieve the piano 
technician stuff.
