Hello Glenn Crashvalve!
I challenge you to wrap a string round a wrest-pin where there's an =
agraffe and then hammer the pin into the pin-block without putting a =
kink in the speaking length of the string. If you can do it I'd like to =
know.  ;-)
Regards
Michael G (UK)

  Baldwin uses straightened and pre-cut wire simply as a manufacturing =
expediency. These wires are purchased from Mapes to specification with =
each coming bundled in a package of, perhaps, a hundred or so identical =
wires labeled for a specific spot on a specific piano. These are then =
placed in one of several tubes set up so the stringer can pull whichever =
specific wire is needed in sequence as stringing progresses.




I have had a couple of technicians observe the wire is not perfectly =
straight in the last inch of travel into the agraffe, and measurements =
seem to confirm this. The theory is this acts like a shock absorber, or =
a mild kink, and affects the string adversely. In fact strings are =
kinked daily by technicians and they don't re-straighten. I had thought =
Baldwin did this for tone quality's sake, but it's obvious to me on =
reflection that indeed it's just for handling ease. I'm guessing Mapes =
used an industry standard straightener, and i'm still wondering if =
roller pressure on the skin of the wire affects it for ill ?
