I don’t know where to post this and I’m sorry if it’s in the wrong place. I just wanted to ask what is your faith that a piece of 3/4 plywood that overhangs an edge and is unsupported there after won’t cup upwards. It will protrude outwards less than 2” and run along the side of the bench for about 7 inches, and be unsupported anywhere in that area, relying on its own stiffness to hold it flat. What makes me worry that it may cup upwards is that this is part of a workbench top and it will be bolted to the supports centered at 2 3/4 back from that outermost edge. Will the pressure from the bolts cause the edge to rear up? This is a single layer thick top.
