That's a pretty funky plain wire scale. > I came up with the tension for the treble by simply putting the plain > wire info into the program without any bass info, Yea, I get the plain wire stuff. How did you determine the tension and break% of those bottom three notes you mentioned without measurement of the bass strings? That's what confused me. Realistically, a scale ought to be evaluated intact. Looking at the entire scale tells you where the tension discontinuities are and how extreme they are. Evaluating just the wrapped, or just the plain strings doesn't give you much of a clue as to how they'll work together in the piano. You really ought to revise the entire scale, or hire it done, as a unit. Ron N
