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) ----- Original Message -----=20 From: Crashvalve@aol.com=20 To: pianotech@ptg.org=20 Sent: Friday, October 24, 2003 3:05 AM Subject: Re: Baldwin pre-cut string In a message dated 10/23/03 12:31:40 PM, pianobuilders@olynet.com = writes: With this in mind I'm not sure what you mean when you say "a = straighter wire gives truer harmonics." =20 Baldwin uses straightened and pre-cut wire simply as a manufacturing = expediency.

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 ?
