I think, to remove old strings, it is very important to avoid kinking = those, or they will break. When you release tension on old strings, = pull on the speaking length while you turn the pin, so the coil unfolds = straight of the pin. after, you can clean the string with steelwool and = d=E9oxydant (anti oxydant ? what is the english word ?) product. To determine what steel was used in the piano, I would rely on in situ = breaking test, knowing that in a piano, and certainly old strings having = some fatigue of being bent many times, the breaking point is lower than = what you would encounter on the same new string in a laboratory. I = believe in those times the strings were tensionned about a major third = below their breaking point, which is relatively higher a tension than = modern scaling shemes (often a major sixth). =20 By the way, are you from Belgium ?
