This discussion is noteworthy in that this problem has cropped up in rebuilding. A rebuilder that I am aware of copies the scales in pianos that come to them without looking at the scale (usually) to see if it will work. They have had problems where treble wires are breaking all over the place when trying to get them up to pitch or worse, shortly after delivery Now this can happen in bass strings too that are covered with a material other than copper and then a copper string clad string is substituted and you can't get it up to pitch without snapping it.
