[CAUT] restringing problems

[Ward & Probst, Inc]

Is that all the 14 gauge on the piano? If so, I'd look at the wire. It's
also in an area that Knabe used a grain angle on the bridge cap that has
been good for business. Did you reshape the capo in that area and seat the
wire on the capo?

Subject: [CAUT] restringing problems


Several weeks ago I was hired to restring a Knabe grand (around 5' 6"  
or so) that was around 100 years old.  Everything went fine, but  
there's one area that will not stabilize--F#6 to b flat 6, all size  
14 wire.  I've tuned the piano several times, but I keep having to go  
back to the aforementioned area to clean up the unisons that have  
gone flat, some by a considerable amount.

The pins are tight.  The coils are tight.  The beckets are good.  I  
believe the bridge pins are solid (I used fresh Dryburgh superglue).   
Plate bolts are solid.  I tuned the piano again today and it seemed  
that things might hold this time, but I'm looking for suggestions in  
case those notes go crazy again.  The notes above and below are  
stabilizing about as I would expect with a restringing.  I'll be  
going back in 2 weeks to check.  If the problem involved only one  
note/string, I'd just replace the string and see if that was the  
cure.  But there are several strings on several notes.

I've restrung many pianos over the years and never had a problem like  
this.  What's going on?
