Let me see what I can do with a pair of rods at 1/3 and 2/3 the width of the table. I guess my question is, does the truss "pull" the load, or does it "push" the load? It seems in my mind like tightening a tightrope, but by using an interior rod instead of exterior anchored turnbuckles. Is my understanding correct on this? I can cut a couple of pieces of 1/4 x 1" flat steel or even angle and drill them to accept 1/2" rods, but am I spreading the load or compressing it? Also, a double rod setup seems to allow for correction. I wonder if I am gonna rip the cross-dowels out of the mdf top. As suggested, I am going to mount a few pieces of aluminum angle with countersunk screw holes. They can straddle the truss rods.
I will try to get photos of what I attempt.
Finally-- Phil, your work is fantastic. I really like the style of the sign for the stove shop. Thank you for answering my message,
