Yamaha upright hammer spring thread

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
