I always considered this a key weighting issue. This particular instance was at B 1. Checked all friction, whippen, jack and hammer. All good, in fact if anything they were pinned too loose. Tried more lost motion, lubricated jack, teflon on butt leather. Increased key dip. Increased jack spring tension. Nothing worked. Well in the end, with the damper pedal depressed and rapidly playing the note it would fail after about twenty repetitions. Under normal playing, if the jack failed to return under the hammer butt, as soon as you release the damper pedal the jack would slip back under the hammer butt. So I told the client "that's as good as it gets", and called it a day. Driving away, I tried to rationalize that it was an unexplained phenomenon. I could not escape the feeling of failure to solve the problem.<BR> <BR>One thing that was mentioned by someone I can't remember who. What would the key bed have to do with this phenomenon?  <BR> <BR>Steve Blasyak<BR>Orange County Ca.<BR> <BR>Pura Vida</SPAN><o:p></o:p></P> <DIV style="MARGIN-LEFT: 0.5in"> <DIV class=MsoNormal style="MARGIN-LEFT: 0.5in; TEXT-ALIGN: center" align=center><SPAN style="FONT-SIZE: 10pt"> <HR align=center width="100%" SIZE=2> </SPAN></DIV></DIV> <P style="MARGIN-LEFT: 1in"><SPAN style="FONT-SIZE: 10pt">Need to know the score, the latest news, or you need your Hotmail®-get your "fix". <A href="http://www.msnmobilefix.com/Default.aspx" target=_blank>Check it out.</A></SPAN><o:p></o:p></P></DIV></DIV></DIV> <P class=MsoNormal style="MARGIN-LEFT: 0.5in"><o:p> </o:p></P></DIV></BLOCKQUOTE></BODY></HTML>
