The density of copper is 9g/cm cubed so if the copper plate covered the whole of the Expert (top) surface (40cm x 40cm) it would be 1/6th of a centimeter thick. The base is, I guess, 30cm x 36cm so that makes it 1/4 cm thick or 1/10th inch thick.
Ha! You beat me to it. I have just performed a quick calculation, I came up with 2.1mm, so we're in the same ball park.
Oh, and going back to the copper plated issue for the O d'A, copper plating 2mm thick plate would cost more that solid 2mm copper plate.
