Both of those= numbers are pretty stout for D#7. That well could be why they= broke so easily. I would think a 14 ga string would be more in= the ballpark. dave __________________________________________ David M.

I had a treble string break during tuning yesterday (D#7) on a= 1975 Kimball console, right next to E7, which had also= apparently broken years ago (and was fixed by easing a tuning= pin's width of string around the hitch pin). Unfortunately,= this rob-Peter-to-pay-Paul approach failed; the string broke= again at the becket long before it got up to pitch. [Side note: the owner had taught piano and had had it tuned= regularly, so I figured the break was due to metal fatigue at= the becket. I was surprised when it broke again at the new= becket I had just made. Shall I expect more breaks? Does the= steel become brittle over time, like brass? There was a 25W DC= bar plugged in, so little string corrosion (and good pin= torque).] I just bought a multi-anvil, friction, vernier micrometer. I've= measured this string (out of the piano, in different places) at= .037 twice and .035 once. There aren't too many straight= places; the whole piece is only about a foot long. Should I use the biggest size I've measured, assuming there may= be stretching (especially because of the break), or do I need= micrometer lessons? (Hmm, I should measure the strings on both= sides, in the piano...) Thanks... --Cy Shuster-- Bluefield, WV ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
