<DIV><FONT size=2>O, List: may I ask yet again to tap in to your =
collective
wisdom? I need to accurately mic a string, and/or round up or down =
a size,
depending on which is safer.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>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.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>[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).]</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>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.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>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...)</FONT></DIV>

<DIV><FONT size=2>Thanks...</FONT></DIV>
