[pianotech] Damper Issue???

[Gerald Groot]

Yes, it could be in the damper head itself.  Sometimes the wire bend up to
the head is on such an incorrect angle that it causes it to touch a
neighboring string too.  Rare but, I have seen this.  Or it could be loose
inside of the head But, it could also be something different too.  Like the
Vbar.  Have you tried moving the damper off to the side away from the string
(carefully) completely to eliminate the damper by holding firmly?  Is the
damper wobbling in the damper guide rail bushing?  Or, is the damper felt of
the damper next to it, turned touching the neighboring strings by chance?
Just a few guesses from here...  Paper clip laying somewhere?

Subject: [pianotech] Damper Issue??? 

I went for a tuning today of a YC PG-175.  Before the tuning, however, I had
to pull the action to fish out some paper clips.  The tuning was going along
great until I got to note F6.  When you played the note with force, and as
the damper returned to the string, there was a sound that sounds common as
that of the damper wire brushing on the string upon it's return.  Upon
adjusting the damper wire, the sound remained.

Here is what I have deduced.  When I strike the note with force and remove
my finger with force, the sound is there.  However, when I strike the note
forcefully, and slowly remove my finger, the sound is not there.  I am
wondering if it has something to do with the damper wire as it enters the
head, the curve of the wire.  Could that be possible.

At this point, I have left it alone rather than trying to manipulate the
wire by the head and having it break.  Especially if I still may be off base
here.

Help appreciated. 

Thank you, 
Matthew
