adequate <BR>downbearing support against the string load or a board
panel which is <BR>flat to begin with, is the fear that the downbearing
of the strings <BR>(being borne up into by the bridge height) would push
the panel <BR>through flat into a negative crown. <STRONG>But wouldn't
the string plane <BR>only push the board until the string plane itself
flattened out</STRONG>?.</FONT></BLOCKQUOTE>

produce <BR>the same pair of opposing springs (board panel plus string
plane) <BR>that we all grew up calling home, with positive crown and
positive <BR>downbearing. You'd enjoy the same mechanical advantage
either way. <BR>(You'd just have to toss out bridge pins as a coupling
mechanism.)</FONT></BLOCKQUOTE>

<BR>shorts, we have...." a no crown no bearing piano that works, but
<BR>still sounds somewhat different than we're used to, which isn't
<BR>necessarily bad........<BR><BR>.........but not something I'd bet on when
it goes up against the <BR>reigning champ, a crowned board
("Spring'o'Spruce™") with appropriate <BR>bearing.</FONT></BLOCKQUOTE>
<DIV> <U><FONT size=3>Yes I agree. I once tuned a miserable 9 ft
kawai that never really had any fire in the tone . Then one day, when I
had time to kill ,I checked the bearing with a lowell gage . ZIp, nada
nothing. I used a crown string to look at bearing.. Massive Crown.
No bearing. Moral of story. The car looks good but there is no gas
in the tank . The same is true of springy spruce with no bearing.
Looks good but it doesn't go very far.</FONT></U></DIV>
