The main thing that I get from this situation is that a piano which is
seriously flat may have either loose pins or a structural problem. I
would probably not bother tightening plate bolts if I'm not aware of a
tuning stability problem. But then, I've never had a piano go boom!
either.

Which raises some questions: Are nose bolts absolutely necessary to
maintain the integrity of the plate or are they just there to dampen the
ringing? Does it depend on the piano? How does a nose bolt get
stripped?????
