face=Arial size=2>>> *Also Dale brings up the fact that crown on a loaded
board is often <BR>>> imperceptible when there may actually be .010" over
12", for <BR>>> example. I've tried loading punchings and holding a ruler
under my twine <BR>>> to get a better measurement, but I keep getting a
cramp in sixth arm. <BR>>> BAAAAH! Problem solved.*<BR>> <BR>> Well,
yea, but either crown or bearing by itself isn't of much <BR>> use. You need
the combination of the two to tell you what the <BR>> board is actually
supporting. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG><FONT color=#0000ff>Absolutely, thus my
attempt to measure crown and sag in a repeatable and reliable manner;
understanding, agreeing and emphasing that this is one piece of our
puzzle.</FONT></STRONG> </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also, a piece of masking tape to <BR>> hold one
end of the KSE at the rim, with one hand holding the <BR>> other end at the
opposite rim still leaves a hand free to <BR>> slide a calibrated wedge in to
measure crown, in as many <BR>> positions along the KSE as you like, to get a
crown profile. <BR>> Light, you say? LED headlamp, sir.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#0000ff size=2><STRONG>Yep. Tried all that. The
string always seems to pull out of the tape as I insert my calibrated shims
and I just don't feel like I can honestly notice the shims contacting the
string accurately to within a few hundedths of an inch. </STRONG></FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2><STRONG></STRONG></FONT> </DIV>
<DIV><FONT face=Arial color=#0000ff size=2><STRONG>Not that your
method doesn't work for you (or as Rodney Dangerfield said in Caddy Shack
"...but that hat looks good on you"). Afterall, there's more ways than one
to skin a cat that'c chewing on your temperment strips.</STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><BR><FONT face=Arial size=2>> <BR>>> *I would also like to humbly
suggest that we upgrade the way we describe <BR>>> crown. I've heard too
many descriptions of crown as an arc deflection <BR>>> without any
relation to a span, specifically as it concerns setting <BR>>> static
downbearing, which just seems incomplete. *<BR>> <BR>> Then we also
need definitions, and understanding, of the <BR>> differences in methods of
setting bearing on old CC boards, <BR>> old RC boards, new CC boards, new RC
boards, and new RC&S <BR>> boards, all of which are somewhat different,
with the RC&S <BR>> boards being considerably different. We also need to
connect <BR>> crown with bearing, which is seldom done in discussion.<BR>>
<BR><BR><FONT color=#0000ff><STRONG>Yes, let's define, understand, differentiate
and listen.</STRONG></FONT></FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><STRONG>I think this is exactly what
most of us are trying to do. I've been quiet because I have a lot of catching up
to do with the current theory, archives etc, a goal which I've been voraciously
pursuing, but I'm hoping to contribute to this age old attack on these
complex issues; And never has there been a better forum than this list and the
genuine good will of many of us to collaborate. I don't see too many rebuilders
wanting to hold back (maybe a little at times by some :). Rochester was a great
opportunity to listen. I wish I could be in Anaheim with a piano, but the powers
that be want to showcase the West Coast talent exclusively (which gives me a
great excuse anyway because I don't think I could afford to bring a piano
there at this point and reciprocate the gesture of our West Coast colleagues
that came East). Anyway, there's always next year and these discussions will go
on for a long time, I hope.</STRONG></FONT></DIV>
