Have you taken any kind of string bearing measurements? ddf Delwin D Fandrich Piano Design & Fabrication 620 South Tower Avenue Centralia, Washington 98531 USA del at fandrichpiano.com ddfandrich at gmail.com Phone 360.736.7563 From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Don Hubbs Sent: Monday, December 06, 2010 7:03 PM To: pianotech at ptg.org Subject: [pianotech] Inverted soundboard I have a 1990 Baldwin 6000 (52" upright) with an inverted soundboard. The piano was evidently in a very damp environment at one time, since there were several loose glue joints, including the bass bridge to apron and some plywood delaminating in the bottom board . The inversion is severe enough that the ribs near the center of the board are pushing against a back post. The tone is even but weak. Is there any way to flip the soundboard back to its original position without destroying it? Can I just remove some wood from the back post to give the rib clearance and expect that to enlarge the tone? Bearing can be adjusted because of the Accu-hitch pins. Thanks for any suggestions or prior experiences. Don Hubbs -------------- next part -------------- An HTML attachment was scrubbed...
