Robin, <br><br>
Are you sure it isn't the old Samick "flaking" problem with the
center pins? <br>
Just wondering. <br><br>

I've treated a few with protek to good effect so far... I thinking
of doing the whole tray and I'll have to try this method. The
humidity has been high here, consistently in the 60s. That is when
the problem showed up so I presumed... ;-)<br><br>
Thanks,<br>

<blockquote type=cite class=cite cite="">This is slightly off topic
here.But the Samick dampers sticking problem is not caused by
humidity.It is caused by friction heating up a chemical in the felt that
then causes the felt to expand and the flange to stick.The best cure is
50/50 alcohol and water treatment over night followed by re-pinning
and reaming any sluggish
flanges.

<dd>> Hi John,
<dd>> Photographing the install takes lots of light considering that
you want a
<dd>> picture of black parts on black beams. In my case it is worse
because I
<dd>> just put an !*#%&~undercover under my wife's piano. I'm
going to invest in
<dd>> a lot of black tacks for my next undercover job. Has anyone
tried drilling
<dd>> ventilation holes between the board behind the damper tray and
the
<dd>> conditioned cavity between the beams? I've been very tempted
while easing
<dd>> damper flanges, Wurlitzer by Samick strikes again.
<dd>>
<dd>> I think the only reason to do an under the beams installation is
when there
<dd>> is not enough room between the beams to fit the humidifier. I
figure to
<dd>> keep about 3/8" between the baffle and the ribs of the
soundboard. On some
<dd>> pianos th! at is above the beams and on some that is between the
beams. I
<dd>> don't let the bars rest on the beams as that is a potential
source of
<dd>> buzzing. Cut them short if you need to.
<dd>>
<dd>> The electrical cords come folded and tied when you get them.
Just pull out
<dd>> enough to reach and then tighten the twist tie. I then put a
wire clip
<dd>> close to this coil and fasten to the side of a beam. Yes they
say that
<dd>> those can form something like resistance coils when you're
welding but the
<dd>> wattage is much lower, I don't think it's and issue with these
cords. So
<dd>> far I've run the cords over the beams. If anything looks too
close (like
<dd>> ribs) I re-route to avoid and use the clips to secure the wires
from the
<dd>> sides of the beams.
<dd>>
<dd>> Wouldn't unisons going out be more of a rendering issue? Perhaps
not if it
<dd>> was dry. You will enjoy the stability that comes when this
system is kept
<dd>> r! unning.
<dd>>
<dd>> Good luck,
<dd>> Andrew
