Young Chang lyre supports buzzing follow up

[David Ilvedson]

Bruce,

Maybe I missed something, but why not leave it screwed to the pedal box and remove the hardware at the top and just use the rod into a little hole you would make?

>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?
