Would it account for the predominantly middle range changes we experience? Would it explain bearing measurement shifts after major pitch change? I'd love to hear Jim Ellis chime in on this.</DIV> <DIV> </DIV> <DIV>Paul</DIV> <DIV> </DIV> <DIV> <DIV><STRONG>"If you want to know the truth, stop having opinions" (Chinese fortune cookie)</STRONG></DIV></DIV> <DIV> </DIV> <DIV> </DIV> <DIV>In a message dated 03/03/07 19:58:09 Central Standard Time, rnossaman@cox.net writes:</DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"> <DIV> <STYLE type=text/css> .aolmailheader {font-size:8pt; color:black; font-family:Arial} a.aolmailheader:link {color:blue; text-decoration:underline; font-weight:normal} a.aolmailheader:visited {color:magenta; text-decoration:underline; font-weight:normal} a.aolmailheader:active {color:blue; text-decoration:underline; font-weight:normal} a.aolmailheader:hover {color:blue; text-decoration:underline; font-weight:normal} </STYLE> <BR>> Okay I'll bite- <BR>> <BR>> Tuning pins moving up and down or forward and backward? <BR>> <BR>> Sid <BR><BR>Forward and backward, directly in line with the string <BR>tension.
