So, I thought, hey, what happens if I take only 2 pieces of blue board, 1.5 inches thick and glue them together?
Well, lets find out. So, I glued them together, again with gorilla glue, and then went to Home Depot, and bought a piece of 2.7mm plywood. That stuff is less than 1/8 inch thick, about .100 of an inch thick, instead of .128.
Next step, (pun intended), is to support them about 30 inches apart, and see what happens.
You guessed it - nothing but a little more bow in the center. So, now we have a 3 x 6 x 30 inch sandwich, which didn't break when I stepped on it.
