Was that a solid bridge root with a ship-lap joint, or vertically laminated? I've also been curious through this thread, about the new Steinways you've examined and found no crown in the mid-treble. These were pianos you were called in on presumably because of just the tonal problem mentioned in Terry's initial thread. Pianos new enough to convince you that they let the factory with deformed boards. How many were these? And how many new Steinway pianos have you been called in to examine because of perfectly fine tone, in which you found the required crown. Or if this is too small a sample (being maybe less than one), compared to Steinway's annual output. This ratio would answer whether the the disappearance of crown is system-wide and due to a procedural decision from the engineering department, or simply as John suggests, from garden variety "out-of-tolerance" work on the floor. I'm also glad to see John back on the list. Bill Ballard RPT NH Chapter, P.T.G.
