<DIV><FONT face=Arial>Some belly designs incorporate soundboards that =
have a
relatively small amount of crown. By the time you string it up with some =
downbearing, many of them will exhibit little if any crown at =
tension -
that is no problem, within the constraints of that design type. That is =
why you
always want to look at downbearing and crown to evaluate =
whether a
soundboard is functioning as well as the design will =
permit.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I wouldn't feel comfortable building a board =
like that,
but many do.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>But a board with a quarter-inch negative crown =
and tons to
downbearing is a no-go in my mind.</FONT></DIV>
