[pianotech] Pedal squeak

[Dean May]

Yes, there is. The brass pedal is just a thin piece of brass adhered to a
steel substructure and it will start squeaking at the connection. Invert the
pedal, spray with accelerator, apply a generous amount of CA glue. Or better
yet, mix up JB weld if you can work any between the two pieces.

I've solved enough pedal squeaks to write a book.  But this one was tougher
than most.  Is there an inherent problem in Young Chang consoles that tends
to produce squeaks?

I thought the squeak was the worn out pedal bushing under the sustain pedal,
so I replaced it.  The squeak came back.  So I did a number of other fixes:
tried to tighten the case board below the pedals which is screwed to the end
case pieces with small screws through a piece of metal (the whole bottom
board flexes when using the pedal), replaced the worn out bushing on the top
of the sustain pedal pole, tightened the loose bases on which the action
rests, and lubed the sustain pedal with dry teflon.

After much testing the squeak is not now apparent.  But I don't know what
fixed it, if any of those did.  And that's no good.

I've worked on other Young Changs, but this is the first Young Chang console
I've seen.  So I'm wondering if there is a theme typical of them.
