Very often, because some = things are difficult to change, and don't get changed unless there is a = pressing reason - like KR - one will conclude that there is no difference between the = two choices, but what one really means is that you can work with either one = - but, one may be more preferable. My guess is that you are going to be better = off with the ideal KR (of .50?) and adjusting the knuckle or other parameter as = needed (pure guess though). I'd sure like to follow through how this shakes out = though.</DIV> <DIV> </DIV> <DIV>Terry Farrell <SPAN = id=__#Ath#SignaturePos__></SPAN> </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=davidlovepianos@earthlink.net href="mailto:davidlovepianos@earthlink.net">David Love</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, July 09, 2001 = 11:24 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: Key ratio/knuckle relationship</DIV> <DIV><BR></DIV> <DIV><FONT size=2>Terry:</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>This came up in a thread awhile ago in which = Stanwood participated.  I had inquired about a problem with a Steinway action.  I was just becoming familiar with David's system.  = Bill Ballard at one point commented at one point (to paraphrase), what's = the difference if it's a .55 key ratio and a 17 mm knuckle or a .50 ratio = and a 16 mm knuckle, none really.  In practice it seems that there is no difference.  The larger arc scribed by the capstan with a KR = of .55 is compensated for by the smaller arc scribed by the 17mm knuckle and = vice versa.  Well now, given the opportunity to make a choice by = moving the balance rail, I'm wondering if there is a benefit to one over the other.</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>David Love</FONT></DIV> <DIV><FONT size=2></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=mfarrel2@tampabay.rr.com href="mailto:mfarrel2@tampabay.rr.com">Farrell</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> July 09, 2001 7:41 = PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: Key = ratio/knuckle relationship</DIV> <DIV><BR></DIV> <DIV>Have you considered consulting with David Stanwood?
