<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">I don't believe these pins will back out. The wedge in the bottom makes them a bit thicker at the bottom than the top. So I would just loosen enough to remove coils, clean up, set all the beckets in line with one another, and restring transferring coils to the existing pins. <div><span class="Apple-tab-span" style="white-space:pre"> </span>I have often puzzled about how they strung these in the factory (something to think about while tuning the one in my client base), and it has seemed to me that it would be pretty hard to come up with a way that didn't start by the pins installed in the web, plate reversed (something supporting the tops of the pins), then wedges pounded in, then plate turned upright and installed in the piano, then strings installed in some fashion (coiled in place, or coils transferred to them). I can't imagine a way of getting those wedges in efficiently with the plate in. I guess some form of long-necked plier to squeeze them in, maybe. But the idea of making a coil on the pin, putting it in the hole, and then adding the wedge, well, it just doesn't compute for me. I wish there was an old-timer around to ask. I've long been curious.<br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Regards,</div><div>Fred Sturm</div><div>University of New Mexico</div><div><a href="mailto:fssturm@unm.edu">fssturm@unm.edu</a></div><div><br class="webkit-block-placeholder"></div></div></span><br class="Apple-interchange-newline"> </div><br><div><div>On Sep 12, 2008, at 6:08 PM, Clarence Zeches wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div><font face="Arial" size="2">Years ago I had an upright with these pins.  I was going to restring it until I realized what the system was.  It was amazing that the tuning pins were very tight.  I think if you back out (down on a grand) the screw a little to loosen the tuning pin then put the new string in and do your normal wraps, then tighten the screw up again it will work.  The stringing would be like a normal string replacement with the tuning pin already in the piano.  I have no idea to the amount of time to restring one.</font></div><div><font face="Arial" size="2"></font> </div><div><font face="Arial" size="2">Clarence Zeches</font></div></span></blockquote></div><br></div></body></html>
