Hi Dean.. One question I have right off... Given that a pianostring would <<elongate>> the 0.127 mm mentioned below (.005 inch), what practical difference would this make to the pitch of the string ? Its not like the distance between the terminations is changing. The diameter would decrease ever so slightly... have a hard time imagining that that would even figure into the picture but perhaps I am wrong... which leaves only a reduction in tension due to this elongation accounting for any pitch change.... which would always go downwards unless there is some kind of reverse elongation that can happen when you lower tension as we often do after a summer... And if its a change in tension due to an elongation process.... well that kinda sounds in layman speech like stretching to me. Got some encouraging words for a itch on my left temple ? Cheers RicB I don't think this degree of plastic deformation stands in the way of the "strings don't stretch over the long term" idea. First, keep in mind the amount of stretch cited here. Even at the 300 pound tension, the plastic deformation was given as about 5 thousandths of an inch. Maybe significant in some way, but it sure wouldn't account for any "winding up of wire on the tuning pin." Agreed. The sample wire size was 6" long so for a 30" wire your .005" would end up as .025". But we are talking pretty small movements of the tuning pin. Dean
