<DIV><FONT face="Bookman Old Style">Paraphrasing from the weeks
discussion:</FONT></DIV>
<DIV><FONT face="Bookman Old Style"></FONT> </DIV>
<DIV><FONT face="Bookman Old Style">Steinway NY builds CC boards, and most
everyone else on the planet builds RC boards. A few of us small shop
rebuilders are designing, building, and installing RC&S boards.
Currently, I don't think there is a RC&S board piano being produced
commercially. I expect that to change, hopefully soon.<BR></FONT></DIV>
<DIV><FONT face="Bookman Old Style">RC & S does not require the
soundboard panel (and ribs) being dried prior to glue-up to the
extent that the classical RC method calls for. RC&S needs no
help from panel compression to support string bearing.<BR></FONT></DIV>
<DIV><FONT face="Bookman Old Style">The purpose of designing crown into an
RC&S board is to provide an opposing spring for the string downbearing,
just like with RC and CC boards (and to prevent cracking in the dry
seasons). The difference is that the crown support comes pretty much
entirely from the ribs in the RC&S boards, and either partially or
entirely from the panel in RC and CC boards
(respectively).<BR></FONT></DIV>
<DIV><FONT face="Bookman Old Style">Hope it helps.</FONT></DIV>
