You’re absolutely right about the quality and also the cost. I have made a few dozen of these floorboards by now and I won’t make them from anything but marine grade A-B or A-A plywood. It’s the only plywood that I’ve cut on my router that I haven’t found voids between the layers. I could reduce the price of the plywood products I make by using less expensive material, but it would be a significant reduction in quality and the thickness would not be correct. Another thing I’ve learned… Plywood is hell on router bits, due to the glued layers.
