What are you looking at? Bearing and crown. When both are evident and measurable everywhere you can get to measure, you more likely have a viable structure. >When I > listen to an old piano and I hear good sustain and dynamic > range, I think we have a good board.

These pianos all showed zero or negative crown in the killer octave, and barely measurable to negative bearing. Assessed by sound alone in May, they would show the true realistic condition of the soundboard in January, after the rebuild. Ron N
