Yes indeed you are right John. It has the plates that are loose - but =
being that the secure the pins, does that not mean the pins are loose as =
well? (ha, ha) As Richard pointed out, it looks like some have migrated =
into the neighboring flange bushing - I've seen that before.

Regarding pushing the pin back in - I've tried that, and I guess I have =
knocked enough bushings out now that I tend to just repin it and not =
worry about pushing the bushing out of the flange. Maybe your luck is =
better?

  Hi Terry,
  This Yamaha, probably has the plates with a screw to hold the pin in =
place.
  These screws should be snugged up, to stop the pin from wandering.
  It is not so much a loose pin that is causing the problem, it is the =
loose plate.
  Sometimes the pins can just be pushed back in place with no damage, if =
you loosen the plate a bit more.
  Then just tighten the screw. Problem solved without repining.

    That was actually the problem. When I first saw it I figured the guy =
chewed up the flange bushings with this innovation, but I repinned it =
with an 0.048" pin - so no enlargement there. The long unclipped end =
interferring with the hammer shank wanting to return to the rest postion =
is what caused the inoperable key. I could see that at least half of the =
hammer flange center pins were walking out of their proper postition on =
this piano - presumably I'll have a repinning and general action =
refurbishing job on the piano. This particular piano was the worst =
Yamaha I have ever tuned with respect to stray string noise (my =
experience is that Yamahas are usually a pleasure to tune) - more like =
tuning a Kimball console (false beats and unisons that would just not =
come clean - I hate that).

        Great new center pin design. This (below) was recovered from a =

all for improvising, but this is ridiculous! Terry Farrell
