I'm planning to open up the gear towers (only connecting the center and lower lightening holes), but am considering a different approach to restoring the lost strength from removing the web than I have seen on other builder's web sites. Rather than completely plating over the open hole, how about an H-shaped plate that would essentially restore the cut-out web? The cross-bar section would incorporate the radii of the mid and lower lightening holes with the vertical legs extending to approx. mid-point of the holes. I'd probably use .063 mat'l for a little extra stiffness with bolt spacing about 150% of existing rivet spacing. Haven't worked out actual dimensions yet; just a concept so far. The primary benefit would be eliminating the multitude of nut plates. Also, the lightening holes would still be there for access to anything that might not need the larger opening.
