[pianotech] Damper Issue???

[Matthew Todd]

One more thing I forgot to mention,
 
I have adjusted bass damper wires from "buzzing" on the string.  In most of those situations, I remember I can just play and sustain the note, and after a second the wire would touch the string sooner or later to cauze the buzz.
 
If I were to descibe the noise that this issue gave me today, I would say that is sounds similar to when you play a note, and then lightly taking a finger with your other hand, and with your fingernail, lightly touch one of the strings that is sustaining.  Does that make sense?
 
In the situation I had today, I could sustain the note and it was fine, but the second I release my finger from the key sharply, I would hear the noise as the damper returned to rest on the string.  If you remember me saying earlier that in order to manipulate the noise, I needed to release my finger from the key quickly.  But releasing my finger softly, there was no noise.  So, I am gathering that by releasing my finger quickly, it is causing the damper to return quicker and more forefully, and therefore the damper wire bend close to the head is in some way contacting the right string.  Unfortunately, I did not think of this until after I left.  I have set another time to return, in the meantime, I have muted that string.

Does this possibility sound reasonable?

Mute the right and middle strings. E.g., if the "V" is the mute, like this:  |   | V |  
If the noise still occurs, you have something in the damper head. If not, it's the wire contacting the string. The wire coming out of the damper head would not make a ringing sound like I'm interpreting from your description.


If the wire is too close to the damper wire, you could move it over slightly. Check first to see if the strings are spaced properly.


If that won't work, someone on the list recently described how to move the hole in the guide rail. I'd rule out everything else first. Check 2 or 3 times to make sure it's not something else.

Ger,
 
How could I troubleshoot the vbar, or the wire being loose in the damper head such as you mentioned?
 
It is the right string of the note that is being affected.  That is the side of the damper wire of that note.  And, after using my damper wire bending tool to bend/manipulate the wire, it was unsuccessful.  I am thinking it could be the bend of the wire toward the top as it enters the head.  Is there a way to troubleshoot that issue as well?
 
Thank you for your help!

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?
