I had not heard of that. I have heard that on some 9' pianos the keys are long enough to flex significantly on a hard blow. Is this new since the 1930s? Did keys get smaller in cross section? Is this related to overall lower string heights on some pianos? ---------- Yes. They lost their bottom plates to make room for the half-round. This detracted from the overall height of the key and, since the key is a relatively simple end-loaded, center-supported beam, it lost a considerable amount of stiffness. And, no. I don't see how this would be related to the lower string height of a piano. > > Spent several hours today sharpening hand plane blades. Took a little less than one millimeter off the back side of my soundboard panel #1 the other day. Let's just say its not a showroom job. Bit of an art this planing thing. Funny how clear that is to me now. And I think I will make it a point to have all the rising grain run the same way of individual boards next panel also. Mix and not match makes for a bit of a challange! ---------- Plane & learn, I always say. Del
