I have resawn 3 x 10 curly maple into two book-matched boards to make a 20″top. One board has a nasty bow (~1/2″ at centre of 60″ span), the other is perfect. If only the figure was not so stunning!
The case is not that rigid and I am concerend that the bowed board will cause teh top and case to distort over time.
I am thinking of machining two dados on the concave side of the board (say 7/8′ wide, 3/8″ deep), over correcting the bow (with clamps) and cementing cherry strips into the dadoes with epoxy. The hope is that as the board is released, the cherry (in compression) will compensate for the natural bow.
I am taking a flyer on the dimensions of the cherry strips (assume that cherry is significantly less elastic than soft maple) and the bend of the board.
Has anyone tried this / similar or are there other ideas?

Maybe you can try this.
Install an aluminum square cross secton beam to the case top. Screw the bowed board to it.
