Oh, I did not understand that the bench was adjustable. Sounds pretty
awesome. But how, after the action is properly bedded in the piano, do you
properly bed the action on the bench? Assuming the action frame has some
flexibility, I should think the action frame might simply assume a different
curve as one or more of the rails. Now if the action was finely regulated
(level keys, etc.) before coming out of the piano, then you could use the
key leveling to level/adjust your bench. But then, if the action was finely
regulated, why take it out of the piano? I guess its really only the key
level that would need to be right on to evaluate whether you had the bench
adjusted right.

Pretty neat idea. It is amazing what we will try! I still like my table.
Each regulating tool when dropped/set on table excites its own unique set of
partials!
