When I first saw it I figured the guy chewed up the flange bushings with this innovation, but I repinned it with an 0.048" pin - so no enlargement there. The long unclipped end interferring with the hammer shank wanting to return to the rest postion is what caused the inoperable key. I could see that at least half of the hammer flange center pins were walking out of their proper postition on this piano - presumably I'll have a repinning and general action refurbishing job on the piano. This particular piano was the worst Yamaha I have ever tuned with respect to stray string noise (my experience is that Yamahas are usually a pleasure to tune) - more like tuning a Kimball console (false beats and unisons that would just not come clean - I hate that).</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Terry Farrell</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A title=Richard.Brekne@grieg.uib.no href="mailto:Richard.Brekne@grieg.uib.no">Richard Brekne</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">Pianotech</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Saturday, September 13, 2003 4:10 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: New Center Pin Design</DIV> <DIV><BR></DIV>Terry <P>you gotta love it... ... the fellow / gal was clever enough to screw the darned thing out and put it in again.... but not clever enough to snip off the leftover clip... wunerful...:) <P>Farrell wrote: <BLOCKQUOTE TYPE="CITE"> <STYLE></STYLE> <FONT face=Arial><FONT size=-1>Great new center pin design.
