Rebuilding for Performance or Show?

[Farrell]

Flexible keys? 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?

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!
