The plot thickens... :-) ----- Original Message ----- From: "Mike Spalding" <mike.spalding1 at frontier.com> To: pianotech at ptg.org Sent: Tuesday, December 7, 2010 8:27:11 AM Subject: Re: [pianotech] Inverted soundboard Here's one possible imagined explanation: The panel that went into that compression-crowned board was not fully cured, or not completely dried down prior to ribbing. Didn't have enough compression to crush wood cells during the wet season, and shrank as it dried and cured to produce negative crown instead of cracks. Commonly seen in "flat-top" guitars when the maker doesn't pay attention to shop humidity during the build. Mike -------------- next part -------------- An HTML attachment was scrubbed...
