This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hello Glen & Del This pre-cut string is a strange idea. I thought pianos were always = strung up from, as Del says, spools of overhead string. But I'd like to add a little something a-propos the kinks or bends in = string. I have a policy when tuning an old piano, and whenever it is = possible, to use the old string by simply loosening off its companion, = straightening out the old string where it had been on the hitch, and = threading it up to the old wrest-pin and tuning up. I find that when = doing this the tonal quality stays the same and they don't stretch like = a replacement new string. You just land up with maybe two coils or less = on the two wrest-pins in question. The strings eventually straighten out = pretty well. I find using a "mole-wrench" on the hitch pin a good idea = to hold the string in place while fiddling around with the loose end. Is = "mole wrench" an international term? It's an adjustable gripping tool = which can grip with incredible force if needed and is adjusted by a = knurled knob sticking out of the end of one of the handles. Good = description? :-) Michael G (UK) ----- Original Message -----=20 From: Delwin D Fandrich=20 To: Pianotech=20 Sent: Thursday, October 23, 2003 5:31 PM Subject: Re: Baldwin pre-cut string ----- Original Message -----=20 From: Crashvalve@aol.com=20 To: pianotech@ptg.org=20 Sent: October 22, 2003 5:13 AM Subject: Baldwin pre-cut string When I visited Conway in 73' they had precut and straightened wire to = string the verticals. I know a straighter wire gives truer harmonics, = Question is; does zig-zag roller straightening of piano wire have any = downside like false beats etc ? If rollers are good, did Baldwin use = then in two or four planes ? regards Glenn C.=20 Unless there is a kink in the wire, any wire stretched to 150+ lbs of = tension is going to be pretty straight. 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. 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. The grand pianos are strung from standard 5-lb coils in rack held above = the piano. Del ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
