Are you finding that this crack allows the board on the bridge side of the crack to be pressed down lower then the other side? I think you'd need to repair any board/rib separation (Tightbond ought to be fine), and then encourage the use of climate control. I assume that you're not considering tearing down the piano and shimming the board. If all of your glue joints are solid, I think the crack itself is more of a cosmetic concern. I second David's suggestion that you contact Don Mannino. (Esp. on a newer instrument) Gordon Large, RPT >> Thank you, Gordon . Your suspicions are correct about the location of this crack. What concerns me most is the death of the tone due to the bridge separating from the soundboard. I'm assuming that the tone will improve once the epoxy closes the gap. I intend to lower the tension on all the strings, move the strings that are in the way, and fill the crack in the board and under the the bridge with a wood colored epoxy. I'll wait the appropriate amount of time, replace the strings and tune, tune, tune. I've done similar repairs to loose bridges and soundboard cracks, just not this combination! Thanks to all of you for your help! Sincerely, Laura
