I have a 93 x 50 x 2 inches Black Walnut island top. I am having trouble getting the island I need due to the COVID-19. So the top is flat on the floor and has been for about three weeks now and is beginning to bow. I have put some weight on it. This is causing some anxiety, what else can I do? Edge grain is the side of the wood board. The boards are cut into strips, turned on their sides, and connected together. Each board is 1.75" wide.
