>>This piano was restrung about 10 years ago. Is it possible the wound strings >>were made improperly? I'm thinking that the bass/lower tenor section needs to >>be rescaled, or at least from B flat 2 to E flat 3 (on treble bridge). I'm >>looking for the most economical alternative here. Is it possible that the original were iron wound? Iron has a lower specific gravity than copper, so copper strings wound to the same dimensions will have a higher tension than those wound with iron. I've run into this problem before on a Knabe upright - went through two sets (of tenor bichords) before Al Sanderson clued us in to the problem and supplied the correct copper diameters. As I recall, the offending strings were at just over 70% of breaking point, and Al recommends no more than 66% If you'd care to send me the specs for these strings, I can work out replacements for you. Ideally, of course, you would be replacing all the wound strings, so they could be rescaled to match the new tenor strings. You can e-mail me directly for details.
