He could have used that same piece of cherry on the outside and 2x4 underneath and just screwed them together, then put in a 2x4 leg in the middle of them and slid it under the outer edge of the table. Then he wouldn't need to store that monster piece of 3/4" plywood, just the piece of cherry/2x4 and the 2x4 leg.
