<DIV><FONT face=Arial size=2>Andrew, </FONT></DIV>
<DIV><FONT face=Arial size=2>I understand the affects of humidity changes and
temperature control within the piano environment and I will take your advice and
re-measure the tuning pin/pinblock situation when the climate change has
stabilized. A Edward's Wool cover is an excellent idea and I will propose it to
the dealer who is storing the piano. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Why would any manufacturer have established dealer
outlets in areas that conditions negate warranty issues? You make it sound like
everyone in the Mohave area has piano's coming apart and rendering them useless.
To our benefit here everyone keeps their indoor temps constant within 5 to 7
degrees year around. I agree a DC unit would protect the moisture content within
the wood components but as soon as the piano is scheduled to perform it has to
be removed for it's protected environmental control and into the fire causing
myself and the other tech's big stability headaches prior to the concert and
usually there is not enough time allowed for the piano to acclimate because
performance venues here don't have the dark time or room enough to place the
instrument. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I originally learned piano technology and had a
business in Maine where drastic changes in humidity from sometimes 70 to 80
percent in the summer and then homes get sealed up in the winter and dried to a
brittle 3 to 5 percent with wood and coal heating would be a constant
unstable situation. Those conditions I noticed had more of a devastating
affect and constantly stressing the wood, glue and fasteners holding everything
together. Plenty of job security there but the pianos lifespan is dramatically
shortened. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>In Las Vegas I recommend a DC system to everyone
and moreover to those with older instrument coming form other parts of the
country where the environment was wetter. The new pianos that are delivered
here have done well to survive and the manufactures are accommodating enough to
provide well built instruments to survive this somewhat environment. The Chinese
pianos do not fare well, however, the Pearl River instruments are doing much
better than the previous years. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks for your advice! </FONT></DIV>

<DIV><BR></DIV>David,<BR>RH greatly affects tuning pin torque. 50-60 %
may read OK while 8% will read inadequate. You may have to re-measure
again in the dry season. That is <B><I>way</I></B> to wide a
swing. This piano needs a cover and a DC Piano-Life-Saver-System under
it. That swing will destroy pinblocks, soundboard, bridges
(bridge-pinning) etc. There are daily (temperature related) swings that
also affect the tuning. The DC system will control those and allow the
piano to be in a concert-quality tuning for more of the time. If they
won't keep a cover on it, get them to use an Edwards string-cover. The
wool will (on its own) help to contain humidity swings and with the DC system
protect the entire piano, extending the conditioned environment into the
action cavity. Without this added protection you are facing an
impossibility. I suspect the numbers you have provided will negate any
warranty.<BR><BR>Good luck,<BR>Andrew Anderson<BR> <BR>At 10:03 AM

<BLOCKQUOTE class=cite cite="" type="cite">Patrick,<BR>Oh yes, I also plan
on a fine tune procedure after I take all of the torque measurements I fell
necessary. I agree with you in that the tuning process helps us become more
intimate with the condition and idiosyncrasies of all the components
involved. Then, perhaps, I can express any thought's I might have as to the
pin tightness problem to the builder.<BR><BR>I don't have a digital type of
instrument to measure humidity. We usually have stable levels around 8 to 18
percent RH. Currently we're in a monsoon weather pattern and levels are 50
to 60 percent. It won't last long.<BR><BR>I did send the pic's to
files@ptg.org so hopefully they will be published.<BR><BR>Thanks<BR>David
