I think that I am beginning to understand why Philco 20 grills are so fragile, if that's the sort of plywood they used. A thick core laminated by two thin layers of veneer on either side. Had they used several thinner layers, each with the grain alternating 90 degrees to each other, they would have been much stronger.
