pin block questions

[Don]

Hi Roger,

If the piano is standing in tune then the pins are tight enough. I do think
that the back side system will take much longer to have a "effect" on the
pin block than the front side systems. I've only installed one backside
system--but it took much longer to see any pinblock effects on that unit.
The piano I did had no "holes" thru the soundboard to allow the moisture
thru it.

I am also seeing pinblock effects (improvements) in grand pianos with
bottom covers.

I do use a cover from the very top of the piano to the very bottom--not
just enclosing the sound board areas.
