Hi Dave,
Take the ser. # and check with Yamaha, it may still be in warranty. If =
so they would probably supply new flanges.
Otherwise a set from Schaff #3809 is $32.83.
Although there was a rumour that they are no longer allowed to sell =
Yamaha parts, because of the grey/ wet problem. I don't know how true =
that is.
If some broke the rest will break within a short time.
Fishing line or dial cord make an acceptable substitute. Determine the =
length and get a suitable piece of dowel, wrap around for how many you =
need and slice with a razor blade.
Make a jig a piece of wood with two nails the proper distance apart, put =
the screw hole of the flange in one and wrap the cord around the other =
one, gluing them in the previously cleaned slot where the rotten one =
was.
The butt flange cord is also available at Schaff #3843, it comes in 14 =
ft lengths @ $1.28 ea.
Good luck.

  Subject: Yamaha upright hammer spring thread


  Hello list,=20

  I recently encountered a problem on a late model P-2/P-22 (not sure =
which....:-) Yamaha upright that is in a church choir practice room.  I =
was called in to repair some "notes that don't work."  Pretty nebulous =
problem, no?  I got there, and discovered that several of the threads =
that hold the tension in the hammer springs had broken.  I removed the =
offending hammers and a hammer with a good thread to get a sizing model. =
 I barely tugged on the thread, and it broke right in the middle, where =
the spring pulls it taut.  =20

  I did not have any of this type of thread available, so I found some =
fairly hefty sewing thread, braided it as best I could for strength, and =
repaired the broken ones with it.  I figured that at some point soon, =
all of these would have to be replaced.  The piano couldn't have been =
more than 5-6 years old.  I would expect a piano made for institutional =
purposes to be far more durable than this.  =20

  I've seen older P-22s last forever.  The new ones seems to be =
constructed of lesser quality materials.  Any comments?  Does Yamaha =
sell this thread/cord/string by the spool?  =20

  Thanks,=20
