<div> Joe:<br> <br> <font face="Arial, Helvetica, sans-serif">"Thin spots" are "necking" of the string and lead quickly to breakage since necking happens only when one reaches to or beyond the elastic limit (Young's modulus) of the string. It's why I don't use wire rollers, too! Generally, one has to think in the range of 300 cents overpull to reach breakage (a minor 3rd). In my opinion, there is never any good reason to overpull strings by any more than 20-40 cents; even 100 cents is excessive. <br> <br> Paul<br> </font></div> <div> <br> </div> -----Original Message-----<br> From: Joe And Penny Goss <imatunr@srvinet.com><br> To: Pianotech List <pianotech@ptg.org><br> Sent: Tue, 8 Apr 2008 5:13 pm<br> Subject: Re: sharp tuning<br> <br> <div id="AOLMsgPart_2_59174309-4e95-4637-b8e4-d9f1778e7ac4"> <div><font face="Arial" size="2">Hey Paul,</font></div> <div><font face="Arial" size="2">Only credit me with the Elastic line.</font></div> <div><font face="Arial" size="2">Me thinks it should have been stated ALMOST TO as stretched to the point that the wire thins out in spots.</font></div> <div><font face="Arial" size="2">Like in the use of the wire roller.

"Beyond it's elasticity" means that the string will now break. Overpitching a string will not cause false (real) beats in and of itself unless there is some bridge involvement. And chipping a piano even a half-step high seems to be way more than necessary. I have typically chipped the piano about 25 cents sharp, watched it fall, then chipped it again 10 cents sharp before actually tuning it, with very stable results. <br> <br> Paul<br> </font></div> <div><br> </div> <div><br> </div> -----Original Message-----<br> From: Joe And Penny Goss <<a href="mailto:imatunr@srvinet.com">imatunr@srvinet.com</a>><br> To: Pianotech List <<a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a>><br> Sent: Tue, 8 Apr 2008 12:46 pm<br> Subject: Re: sharp tuning<br> <br> <div id="AOLMsgPart_2_10bdabfd-68d5-45ad-9ad7-f302ea97f5b1"> <div><font face="Arial" size="2">Hi Wim,</font></div> <div><font face="Arial" size="2">I suspect there will be a slurry of false beating sounds in the upper range of this instrument, caused by over stretching of the wire beyond it's elasticity.</font></div> <div>Joe Goss RPT<br> Mother Goose Tools<br> <a href="mailto:imatunr@srvinet.com">imatunr@srvinet.com</a><br> <a target="_blank" href="http://www.mothergoosetools.com">www.mothergoosetools.com</a></div> <blockquote dir="ltr" style="border-left: 2px solid rgb(0, 0, 0); padding-right: 0px; padding-left: 5px; margin-left: 5px; margin-right: 0px;"> <div style="font-family: arial; font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-size-adjust: none; font-stretch: normal;">----- Original Message ----- </div> <div style="background: rgb(228, 228, 228) none repeat scroll 0% 50%; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial; font-family: arial; font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-size-adjust: none; font-stretch: normal;"><b>From:</b> <a title="wimblees@aol.com" href="mailto:wimblees@aol.com">Willem Blees</a> </div> <div style="font-family: arial; font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-size-adjust: none; font-stretch: normal;"><b>To:</b> <a title="pianotech@ptg.org" href="mailto:pianotech@ptg.org">pianotech@ptg.org</a> </div> <div style="font-family: arial; font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-size-adjust: none; font-stretch: normal;"><b>Sent:</b> Tuesday, April 08, 2008 11:03 AM</div> <div style="font-family: arial; font-style: normal; font-variant: normal; font-weight: normal; font-size: 10pt; line-height: normal; font-size-adjust: none; font-stretch: normal;"><b>Subject:</b> Re: sharp tuning</div> <div><br> </div> <wbr>Noah<br> <br> Who ever restrung this piano really took a chance tuning the piano a whole step sharp. I chip a piano a half a step high, but even my first tuning is only 25 cents high. I don't think this dealer understands what is happening to this piano. Is he telling you to keep it a whole step high because he doesn't want to pay you to do more than just a tuning, or does he think customers won't notice. In my opinion, he is not being honest with him self, much less his customers. <br> <br> <div style="clear: both;">Willem (Wim) Blees, RPT<br> Piano Tuner/Technician<br> Honolulu, HI<br> Author of <br> The Business of Piano Tuning<br> available from Potter Press<br> <a target="_blank" href="http://www.pianotuning.com">www.pianotuning.com</a></div> <br> <br> -----Original Message-----<br> From: Noah Haverkamp <<a href="mailto:noahhaverkamp@yahoo.com">noahhaverkamp@yahoo.com</a>><br> To: <a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a><br> Sent: Tue, 8 Apr 2008 2:01 am<br> Subject: sharp tuning<br> <br> <div id="AOLMsgPart_2_5d28bc90-d1bb-4288-bc02-5089c763eac4">i began to do a floor tuning at a warehouse last week and A4 was tuned as B4. i tuned it to A440.
