<div>Dave -</div> <div> </div> <div>Did you check that there is absolutely no play between the action brackets and the bolts in the keybed that they rest on? I have found insidious squeaks originating from that interface on more than one occasion.</div> <div> </div> <div>Mark Potter<BR><BR><B><I>piannaman@aol.com</I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV> Hi All,</DIV> <DIV> </DIV> <DIV>I thought I could solve any damper pedal mechanism squeak, and up until recently, I've had pretty good luck. Then I met a recent model Hallet-Davis (Dongbei built, I believe) upright. </DIV> <DIV> </DIV> <DIV>I lubricated and tightened everything I could think of. Here's the list of things I tightened and lubed:</DIV> <DIV> </DIV> <DIV><B><FONT size=2> <DIV>Lubed</DIV> <DIV>damper flange centers (protek CLP)</DIV> <DIV>damper springs
(teflon powder)</DIV> <DIV>damper lever felt with teflon(two weeks prior) and protek last night</DIV> <DIV>lift rod with protek</DIV> <DIV>all rod tips and linkage w/ special blend</DIV> <DIV> </DIV> <DIV>tightened </DIV> <DIV>all screws on the various rails</DIV> <DIV>pedal rod hinge screws</DIV> <DIV>all pedal brackets and fixture screws</DIV> <DIV>all damper flange screws</DIV> <DIV>all available case screws</DIV> <DIV>In addition, I inserted buckskin pieces in places where case parts were rubbing and replaced the rubber pieces where the pedal rod inserts into the lift rod with buckskin pieces</DIV> <DIV> </DIV> <DIV></DIV> <DIV>Noise still thereā¦..argh! It sounds to me like it's the damper lever felt/lift rod interface. It doesn't happen when the pedal is first being used, say for 20-30 presses of the pedal. Then gradually, the creak comes back.</DIV> <DIV> </DIV> <DIV>I don't know what else to do. Did I miss anything? Any
ideas?</DIV></B></FONT></DIV> <DIV> </DIV> <DIV style="CLEAR: both">Dave Stahl<BR><BR>Dave Stahl Piano Service<BR>650-224-3560<BR>dstahlpiano@sbcglobal.net<BR>http://dstahlpiano.net/<BR><BR><BR><BR></DIV> <DIV class=AOLPromoFooter> <HR style="MARGIN-TOP: 10px"> <A href="http://pr.atwola.com/promoclk/1615326657x4311227241x4298082137/aol?redir=http%3A%2F%2Fwww%2Eaol%2Ecom%2Fnewaol" target=_blank><B>Check out the new AOL</B></A>.
