I take it all the problems stated below are new since the weather change.  Look close at key bedding, loose screws, action bracket screws, hammer rail, keys rubbing, key bushings, you get the idea. Sustanuto interference, could be anything, but it shouldn't take 20 minutes to figure out.</FONT></DIV> <DIV><FONT size=2>Fenton</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> Monday, February 26, 2007 5:58 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> new Hamilton</DIV> <DIV><BR></DIV> <DIV>Hi list,</DIV> <DIV>Tuned this new Hamilton grand at dealers just before Christmas. No big deal, not great ,but no real major problems. Went back last week after a prolonged cold snap here in the NE. </DIV> <DIV>Key dip was no more than 8mm and regulation was terribly off as you would expect.</DIV> <DIV>Looked under fronts and found about an average of 8-10 punchings under each key,also key height is off on several naturals.</DIV> <DIV>I'm open to any suggestions besides gasoline and a match to correct.</DIV> <DIV>My first thought is to redo height and dip and then regulate,but could this be a key frame problem? Humidity level has not been over 30% in this room.</DIV> <DIV>RU/UP</DIV></BLOCKQUOTE></BODY></HTML>
