<HTML>Hello list, 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.   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.   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?   Thanks, Dave Stahl</HTML>
