Making the torsion box out of 3/4" is overkill. imnsho. Maybe the
outer perimeter, but the cells and top itself would just as well be
made out of 1/2" (6x6 cells?).
If you're using wood glue on ash veneer anywhere, be careful. The
stuff bleeds through. Go for the paper-backed veneer, much safer and
usually better quality.

Good point. My original sketch had 1/2" all around but I figured it
needed more rigidity in the frame. My reasoning is that the top has
three cutouts sized approx. 15"x15" for recessed mounting of a pair of
turntables and a mixer. Which means I only have three cells over the
whole table span. Would you still use 1/2" for the top and bottom
skins? Here's a rough drawing (top view):
