<DIV>Dale,</DIV>
<DIV>Thanks for detailed info -- some of it will help, although we're not
cutting and drilling these pieces -- we aren't equipped for that level of =
work
and the reason we were sending this stuff to Schaff was so they could buil=
d
these parts for us. </DIV>
<DIV>You mentioned a bearing bar and a counter
bearing.</FONT></DIV></BLOCKQUOTE>
<DIV> <STRONG>Sorry no counter bearing bar. I mis spoke.</STRONG></DIV>

size=2>Not sure how you're defining these two, but there was only one ro=
w of
bearing pins setting the top end of the string between the tuning pin and =
the
speaking length. This is the 'bearing bar' we sent off for reconstruction,=
so
we have no clue about where those pins were. I've considered putting the
action in and running a string as you describe, to line up with the old st=
ring
marks in the old hammers so we could locate the top bearing position.

<DIV> <STRONG>Yes this is also more clues & a way to reestablish t=
he
pin locations > unfortunately I've never even heard or seen a
Carlisle</STRONG></DIV>

could just take a tracing of the bearing bar pins for us. </DIV>
<DIV> </DIV>
<DIV>I'm surmising from other things you said that 2mm is the amount of
downbearing we'd want to achieve at the bridge, </FONT></DIV></BLOCKQUOTE>
<DIV><STRONG> Upright bass bridges are usually cantileverd & also =
so
sitting on a very thin part of the soundboard therefore its wise not
necessary to stress this bridge with excess bearing. It requ=
ires
esentially zero bearing for tone production.</STRONG></DIV>
<DIV><STRONG> That said you don't want negative bearing. If you =
have
2mm you'll be at about zero when acounting for bearing felt & the thickn=
ess
of the twisted part of the loop which doubles the O>D. of the strings cor=
e
diameter.</STRONG></DIV>

<DIV><STRONG>Correct? That's
right.................Dale<BR></STRONG>Thanks again,</DIV>
