<HTML><BODY> <div> I think John's suggestions are correct.  It wouldn't be the damper lever felt, because you take it out of play by using the pedal.  My suspicion is tight front rail bushings.  Easy way to check this is to lift the wippen up off of the capstan  with one hand, and rock the key back and forth with the other to check for tightness.  Compare the sluggish notes' keys with the keys of good notes to see if there is a difference.<br> <br> Next choices would be hammer flange center, jack center, or wippen center.<br> </div> <div> </div> <div style="clear: both;">Dave Stahl, RPT<br> <br> Dave Stahl Piano Service<br> 650-224-3560<br> dstahlpiano@sbcglobal.net<br> http://dstahlpiano.net/<br> <br> <br> </div> <div> </div> -----Original Message-----<br> From: jrpiano@win.eastlink.ca<br> To: pianotech@ptg.org<br> Sent: Fri, 4 May 2007 10:30 AM<br> Subject: Re: Sticking keys<br> <br> <div id="AOLMsgPart_2_e2de515d-a7d7-41f6-80e0-c4b1c6fb4283"> <div><strong><font face="Arial">The fact that it only happens when the damper pedal is used, suggests higher friction for those notes.

Two or three notes stick only when the damper pedal is used. I have checked the damper lever felt for indentions and there OK. Briddle strap wire is clear. Key dip is the same as other keys.  I checked a few other things that another Tech suggested but nothing seems to stop the sticking.
