<BLOCKQUOTE>Just a thought, Should the pinning of the jack be looser than
that of the wippen so that jack's needs are taken care first?<BR>When
Jack is happy!<BR>Joe Goss RPT<BR>Mother Goose Tools<BR><BR></BLOCKQUOTE>Hi
Joe<BR><BR>This is exactly the kind of point I was talking about when I
said.... (more or less) hold on a sec here... There is no point to
simply assuming that repinning the rep - lever forces a change in rep lever
tension in the same direction... i.e. increase/decrease tension and
friction. The point is that you want to end up with all three pins at an
appropriate level of friction so as to facilitate the primary function of the
rep lever whippen assembly while not creating either too much hammer jump
and/or too much key kick. This also gets into hammer weight and key
mass. <BR><BR>In any case... a change of friction of the rep-lever pin
in itself does not re-direct more of the springs force in one or the other
direction. And since the end tension of the spring is dependent the whole
system and not just this pin.... nor does changing the pin dictate any given
change in spring tension.<BR><BR>Cheers<BR>RicB<BR></BLOCKQUOTE></BODY></HTML>
