Young Chang lyre supports buzzing follow up

[Dean May]

Have you tried a couple of drops of CA glue? I would think that would flow
into the joints and fill them up enough to stop any buzzing.

Subject: Young Chang lyre supports buzzing follow up

 

Thank you to many of you will suggestions for helping with this problem.
This was discussed about six weeks ago on this list now.  The problem being
on a Young Chang grand, the pedal lyre supports would buzz as a sympathetic
vibration when some notes were played.

 

After making a close inspection, I could not see any loose parts of the
pedal lyre.  Nothing had come unglued.  I tried moving the two screws that
fasten the top of the supports closer to the lyre.  As one or more people
suggested, if the lyre is pushing on the support, it won't be able to
vibrate freely.  The treble side support was the one buzzing for a long
time.  After moving it closer to the lyre, it stopped.  The other support
then started buzzing; that one was now no longer being compressed, so I
moved it closer.  The first one started to make noise again.  After moving
it a lesser distance closer, they both were quiet enough.

 

I cannot say that I have great confidence in this being a long lasting
repair.  On this instrument, I do not want to replace the supports with
traditional lyre sticks.  It is on a raised stage in a small theatre and I
do not want to drill into the poly finish.  The pedal lyre is at face level
for the audience and anything I do down there will be quite visible.  I may
epoxy that hinge joint so it cannot move.  Is there any reason it needs to
be hinged aside from factory production ease?  What has worked for you?
