Yamaha problem

[Avery Todd]

Hi Mark & others,

   Combining all your responses with comments interspersed.

>Adjustment screw that spaces the action frame away from the plate (in lieu

   It was away from the plate a little, so I adjusted it. No effect on the
damper problem.

   It was very slightly worn but replaced and lubed it anyway. No effect.

>Second is a loose hook.

   Wasn't loose.

===============================

   Wasn't bent that I could see/find.

   On a piano built in 1972? I doubt even Yamaha would cover "that"
under warranty. :-)

==============================

>darn. How do I know. OOPS.

   Not bent. Everything looks in excellent shape.

>The left hand bushing takes a beating over time, most often just rebushing
the clip solves the problem.

   Done.

>Make sure the bass keybed nosebolt is keeping the action secure.  The

   It wasn't, so adjusted that also.

==============================
   Frustrating problem guys and I STILL don't know what the REAL problem
was/is. So, since I had most of the hammers out of the way anyway,
replacing all the flanges, I just went ahead and did a wire bending job.
Hopefully, it won't come back to bite me. :-)
   Thanks to everyone who sent a response. Some good ideas but
unfortunately, none of them solved the problem.

Regards to all,
Avery
