<DIV><FONT face=Arial size=2> Thanks, Allen. =
Actually, it's
quite unsettling to approach a piano in which the whole piano kind of =
"rings",
and not to be able to find any particular reason for it. I did do pretty =
much
what you suggested when I was there, though. I splayed my hand out =
across about
a thirteenth on the strings, and then tried playing a chord in a =
neighboring
region of the piano. Didn't seem to make a difference. That's why I came =
to the
conclusion that it was "pandemic" to that particular piano.</FONT></DIV>
<DIV><FONT face=Arial size=2> I just couldn't =
figure out why
it would ring like that, and not have any real damper function problems. =
</FONT></DIV>
<DIV><FONT face=Arial size=2> I put in a call to =
Kent Webb
today, and never heard from him, but to be fair, I mentioned that =
another tech
was calling on the same topic, so he may have responded to him, and I =
haven't
heard about it yet.</FONT></DIV>

However, you
might eliminate some possibilities by trying some different
troubleshooting. Get a strip of wood (oh say 3/4" x 3/4") and =
whatever
length is easy to work with (12"-18") with a strip of thick soft felt =
glued to
one edge. You press this strip against a large group of strings =
and
eliminate any leakage that the dampers are letting through. This =
works
especially well when a damper leak is occurring at a sympathetic =

the
sympathetic vibration from another note.</FONT></SPAN></DIV>

Ringing<BR><BR></FONT></DIV>
<DIV><FONT face=Arial size=2> I had an odd =
occurrence
today that I really hope that you all can help me with. I had a =
customer who has a new Steinway model 4510 (model 45?) studio, with =
damper
problems. When I got out there, it's kind of a damper problem, but =
not
really. The problem is;</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>A) The whole piano rings, =
when you play a
chord or any note in a staccato fashion.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>B) The pedals are not lifting =
the
dampers.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>C) The spoons are not too early, =
the strings
have plenty of follow.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>D) The dampers are aligned =
properly.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> In short, no =
real problem
with the damper system. What I did notice while working on the =
trapwork was
that if I stuck the plate with the heel of my hand, the whole piano =
would
ring. When you struck the piano anywhere, it would ring. =
</FONT></DIV>
<DIV><FONT face=Arial size=2> I did notice =
that some of
the bi-chords where indented by the strings, but they had =
plenty of
follow-through.</FONT></DIV>
<DIV><FONT face=Arial size=2> The waste ends =
on the hitch
pin side of the strings were already braided. </FONT></DIV>
<DIV><FONT face=Arial size=2> I tried striking =
notes with
my hand on groups of strings, and no effect. I strummed groups of =
notes and
found nothing leaking. And yet the whole piano had a real ring to =
it.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I'm just =
wondering if the
plate, being sand cast, could have warped and twisted enough to =
cause some
weird tension on it which would cause it to ring like a bell. I =
mean, if
something as massive as a plate wanted to ring, could you really =
expect the
energy to go up the strings to be damped by little pieces of =
felt?
</FONT></DIV>
<DIV><FONT face=Arial size=2> I hope that =
someone can help
me out. Tomorrow I call Kent Webb, and see if he can =
help.</FONT></DIV>
<DIV><FONT face=Arial size=2> One interesting =
note here.
This piano was just purchased three months ago. I looked it up in =
the Atlas,
it was produced in '96.</FONT></DIV>
