Is it a good idea to tune on itself a piano outtuned becuse of humidity

[Philippe Errembault]

No, no, the fact that we have the fourth seasons in the same day was a joke about belgian weather ;-) 
but as Stéphane observed, we had a very hot July and a is quite rainy August... I in july I had about 60% 
humidity and now it raised to 80%. thats why I wondered if I shouldn't wait until it's back to 60% before
tuning it to A440 instead of doing it now and have to raise it again in one month.

Now about the dampp-chaser, I just called Taffijn and he confirmed that it would cost arount 400-500?...
but they do not sell anymore, because for benelux, it is now sold exclusively by Orimex in Dordrecht 
(near Roterdam)

So, since I currently don't have one and have, neither the time nor the money to buy one, and since my 
piano has raised because of the humidity, would you recommend to lower it, and raise it again when 
humidity lower again, or to leave it alone, optionaly tuning it on itself until humidity reach 60% again ?

ps: Stéphane, are you sure this year is so exceptional ? I had the feeling that we had the same weather 
as last year - By the way, this is all the fault of american people because they won't sign Kyoto protocol ! 
Now is the time I get killed ;-)

  You said the humidity changes several times a day, didn't you?
  Why not close the back or bottom with a plastic sheet and keep the case closed as much as possible.
  It is possible to seal both bottom and top of a grand piano with plastic sheets.

    Indeed Philippe,

    That is what I would do : install a dampp-chaser to get rid of the humidity swings that no piano likes, and when changing for another, keep the dampp-chaser for the new one.
    Btw, are you enjoying the coldest month of August ever, after the hottest month of July ever ?

    Best regards.

      Well, because I use it !!!

      but with the wooden frame, it moves quite much with humidity variations. 

      the point is the Damp-chaser is probably much more expensive than the value of the piano...
      Now, if I ever have to change the piano, maybe I could move the damp-chaser to the new one !?!

        Hi Philippe.

        If the piano is not worth preserving it, why would you preserve it ?
