Man, that thing would be h e a v y. I would wonder if it would be safe with so much wood on it though.
Heavy is good! I used wood (3/4" ply, 2 X 6 around the edges.) because mine is a lay out and fab table. I have a heavy steel table for welding. Many of my tools are mounted on it, and easy to remove when I need more room. Call it a rat table if you must But it is seriously the best improvement I've made to the shop this year.
