Ron, You make me feel that common sense is just as precious as mystics (or theories, which in a certain sense is exactly the same). Thanks for your valued input. You really help me ascertaining where I'm doing a good job and where I'm just dreaming.

I suppose that any fitting done when the board changes > dimensions again is of no value. Or is this overkill ? It's overkill. The soundboard has to be trimmed enough to go into the piano, but there's no reason it needs to exactly fit the rim at it's edge. I do a rough fit of the panel dried to 6%MC before I glue the ribs on, but am not too concerned what it is, if it's somewhere near, when I install the board. Ron N
