<DIV><FONT face="Comic Sans MS" color=#000080>I would guess that =
most of us
string pianos all the time without putting any noticeable kink out in =
the
speaking length of the wire. Indeed, I would say it would take a pretty =

<DIV><FONT face="Comic Sans MS" color=#000080>There is quite a =
difference
between a kink in the wire -- i.e., abruptly bending the wire enough to =
take the
steel beyond its proportional limit and putting a permanent bend in =
the
wire -- and the gentle curve observed in the wire as it approaches =
its
termination. The extent of this curve is a function of the string's =
stiffness
(its diameter) and the string deflection angle as it passes either =
through the
agraffe or across the V-bar. This bend appears because music wire is not =
perfectly flexible, not because the stringer is putting a kink in the
wire. A similar, though milder bend can seen as the wire approaches =
the
bridge pin offset. Both of these tend to dissipate over time. Or they =
can be
straightened out by one of several string leveling techniques. (Check =
the
archives for string leveling.) Indeed, in most shops, this string =
leveling is
done as a normal part of the stringing operation. Not so much because "a =
straighter wire gives truer harmonics," but because we want the hammer =
to strike
all of the strings of the unison simultaneously.</FONT></DIV>
