> Hi John, Ron, > > How does that (RH swings) affect your center pinning?? Pretty much any way it pleases. I currently do contract work for a couple of colleges, and in all the yeas I've been doing this, I've never done work for an educational facility with anything even faintly resembling humidity control. Without humidity control, the pinning will do what it will do and there's not much I can do about it. Since I'm not on the payroll and work by the hour, there's not a lot of repinning going on anyway, nor specific voicing work for picky pianists. I typically get to try to make them sound passably less bad twice a year just before the major seasonal changes. >When could you > effectively repin?

Pining that's too loose for three months or the year is better than pinning that's sluggish or seized up for six. > This is a concern I've had which I don't remember ever being addressed. > I've just tried to "get by", but there must be some pinning wisdom out > there that I'm missing. I doubt it, unless someone has moisture proof bushings and flanges. Reality has a way of not paying much attention to the way I'd like things. Ron N
