Keytop Trimming Question/Dave Smith

[Dave Smith]

Patrick, you raise an interesting question.  I understand that wood shrinks
and swells with humidity changes.  But is there really a systematic, long
term, significant shrinkage of properly seasoned wood, independent of
humidity effects?  I may be showing my extreme ignorance here, but that's
not a new thing.  What makes me ask is that if the width of the key shrinks
significantly over decades,wouldn't the other two dimensions shrink
significantly also?  Key length and height -  at least maybe height.
