Working on a round chessboard for a coworker. Consists of a base about 2.5 inches thick which will hold the pieces and a top that will have the chess squares set in. After routing out the top for the squares the top has become bowed a good bit. My question is, does anyone think as I glue in the squares, keeping the top flat, that it will help take the bow out? It's got about an 1/8" bow to it. It's a round 18" glue up, roughly 3/4" thick.
