Violin makers would store wood for the next generation.<BR>Cut into pieces for soundboards at least S&S would dry it down to 3% and glue on the ribs. Back in "normal" humidity the soundboard would "crown". Much later YA showed up this as a great new invention though it had been done by European an US manufacturers for decades.</BLOCKQUOTE></BLOCKQUOTE></BLOCKQUOTE></BODY></HTML>
