I'm making a replacement press plate for a small apple press using some edge glued oak boards from a hardware store. The board was flat as purchased, and after acclimating to my shop conditions remained flat until I cut out the required circles. As I cut I noticed them bending away from the board, revealing pre-existing stress in the wood.
My intention is to glue these together into one thick plate, with the grain orthogonal to each other. The press metal pressure spreaders will be orthogonal to the grain of the top piece. I'll be using titebond ii glue with deck screws.
Given the use case of these parts and the cupping present, how should I orient the faces?
Cupped sides both down, up, together, or apart?
