<DIV>Hi Del

<BR> &nb=

I have too much evidence to the contrary. The end of the knot =
becomes a
theoretical termination point, and the helix is almost incapable of
flexing.<SPAN class=359195423-08042005><FONT face="Comic Sans MS"

<DIV dir=ltr><SPAN class=359195423-08042005><FONT face="Comic Sans =

string doesn't
have to flex, it pivots at the hitchpin itself. The twist is of no
consequence.</FONT></SPAN></DIV>

<DIV><SPAN class=359195423-08042005> </SPAN>So many pianos have =
about a
55mm knot at A0, and only about 7-10mm of flexible string. =
James
had a clear demonstration model at the Cal state convention. The =
reaction of all that saw it was wow! The vibration time of the new =
knot vs an
English loop is about 3 times greater.</DIV></BLOCKQUOTE>

<DIV>To the previous writer, it is not Del's hitch pins. But was =
