Two possible causes come to mind. You say it’s an expensive grand so it probably has a green-sand cast plate. Occasionally bits—as in very small clumps—of sand break loose from somewhere and get into the casting. To me this seems most likely. The other possibility is an internal gas (air) pocket. I’d think you’d have discovered that the first time around, though.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Comic Sans MS";color:navy'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Comic Sans MS";color:navy'>ddf<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Comic Sans MS";color:navy'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Comic Sans MS";color:#632423'>Delwin D Fandrich</span><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Comic Sans MS";color:#632423'>Piano Design & Fabrication</span><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423'>6939 Foothill Court SW, </span><span style='font-size:10.0pt;font-family:"Comic Sans MS";color:#632423'>Olympia, Washington 98512 USA<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Comic Sans MS";color:#632423'>Phone 360.515.0119 — Cell 360.388.6525</span><span style='font-size:10.0pt;font-family:"Calibri","sans-serif";color:#632423'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Comic Sans MS";color:#632423'><a href="mailto:del@fandrichpiano.com">del@fandrichpiano.com </a></span><span style='font-size:10.0pt;font-family:"Comic Sans MS";color:#632423'>— </span><span style='font-size:10.0pt;font-family:"Comic Sans MS";color:#632423'><a href="mailto:ddfandrich@gmail.com">ddfandrich@gmail.com</a></span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:navy'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Comic Sans MS";color:navy'><o:p> </o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] <b>On Behalf Of </b>Ed Foote<br><b>Sent:</b> Saturday, December 03, 2011 5:49 AM<br><b>To:</b> pianotech@ptg.org<br><b>Subject:</b> [pianotech] hitch pin hole<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><o:p> </o:p></p><p class=MsoNormal style='margin-left:36.0pt'><span style='font-size:10.0pt;font-family:"Georgia","serif";color:black'>Greetings, <o:p></o:p></span></p><div><p class=MsoNormal style='margin-left:36.0pt'><span style='font-size:10.0pt;font-family:"Georgia","serif";color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal style='margin-left:36.0pt'><span style='font-size:10.0pt;font-family:"Georgia","serif";color:black'>Three years ago, I had a hitch pin begin to give way in the plate of a rather expen$ive grand. It seems that there was a pocket of something other than cast iron at the particular spot (Eb55). It was under warranty. Factory recommendation was to install a larger pin, which I did while accompanied by the dealer's technician. Now, I get a call that the note is once again totally whacked out and I fear that the pin is once again beginning to lean into the string's pull. I think the ultimate solution would be to drill a new hole perhaps an inch farther distally and just avoid the area. </span><span class=apple-style-span><span style='font-family:"Georgia","serif";color:black'> Anybody else deal with something like this?
