[pianotech] Humidity Question

[Tony Caught]

Hi Kent.  Why ??? you could assume that the pianos were regulated after they
were two months old and loose screws is a sign of piano drying out not time.

You are mixing your issues, aren't you? If these pianos are just a few
months old, then they are right on schedule needing action regulation after
an initial playing-in period. The pianos may need climate control, but it
would be a mistake to blame all the action problems of new pianos on the
change of seasons.

Returning after the holiday break to a college I tech for I was surprised to
find lots of action problems.  All pianos are new and are Steinways and
Bostons.

 

The grands have screws which are loosening in wippen and hammer flanges.
Causing lots of clicking and clacking.  Loose enough to need an 1/8 of turn
to retighten and cause some hammers to rub each other.  Also on one Boston
grand hammers were blocking and very nearly blocking in tenor and treble
sections.

 

A K-52 is experiencing bobbling hammers on every note and lost motion seems
now to be excessive.

 

My question is:  Is our low humidity here in West Texas at about 20% RH on
average and the practice room humidity hovering around 21% capable of
causing such widespread fluctuation?

 

Is it expected with these new pianos that these regulation issues will come
up until they have truly acclimated to this new environment?  They have only
been here a few months.

 

For those of you who are Dammp Chaser installers and are experienced with
the results, would installation of this system be a good idea given the dry
climate?  

 

Thanks for the expert help.
