[pianotech] String Breakage

[Arlie Rauch]

I've had the same experience on P22s.  In recent years when I have encountered one of those, I back those two suspect strings off a bit before raising their pitch.  I can't prove that is the reason, but I have not had breakage when using that approach.

I spliced two of them (not easy to do since there is only about 1 inch between the top speaking termination point and the tuning pin.)? And I think a year or two later the splices broke.? I figured it was the severe angle of the string coming off the coil.? On some I've seen the string overlapping the coil.?
