I started work on a leg vise (single screw in the center) for my bench. The chop is a made from a piece of 2x8 SYP. Sadly one face runs almost exactly through the pith of the tree. If the board does cup, I want the edges to move toward the face of the bench so they will compress to squeeze the whole board rather than at just one point if they cupped away. Which way will it most likely cup toward the pith or away?
