I took a bunch of pins like this out of a Korean piano a while ago - whole back action froze up. Don't know what it is, but I figure it either leached out of the bushings or was a product of some sort of reaction between the wood/bushing/pin. Are your bushings black also? If I remember correctly, we put a lot of new action parts into this piano.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><IMG alt="" hspace=0 src="cid:008701c74632$283fd6d0$0501a8c0@DESKTOP" align=baseline border=0></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.ucci@att.net href="mailto:richard.ucci@att.net">richard.ucci@att.net</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Thursday, February 01, 2007 8:36 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> black gunk</DIV> <DIV><BR></DIV> <DIV>List,</DIV> <DIV>While repinning a sluggish balancier on a newish wurly c-143 ( with constant flang seizing problems),I noticed this black gunk on the pin when I removed it.
