My husband created one like has been one like has been suggested only we used matching sets of double drawers that were the right height. He attached a narrow edge to the top front. Then took 3/4 inch 4' sheet of plywood and created a top. We separated the sets of drawers so the 4' would fit across them and the narrow edge kept them in place. He put a piano hinge the full 4' width and added an additional 3x4' leaf that can be lifted up and held with a brace he made. Believe me this doesn't move when cutting. And you can cut almost anything with 4 x 6' space. I have the space to leave it up all the time if the leaf is down.
