I lightened the turner board in my HUGE home built bator so I would have good air flow. Now 24 hrs into the very first set it has bowed under the weight of the eggs to the point that I cant turn the eggs w/o opening the bator. I need a way to strengthen this thing w/o closing all the air space. Maybe I can find some 1/4 angle iron & screw it along the edge? what should I do? Here is what it looked like after I cut the center out.
