I’ve been trying to figure out a good way to bolt a one-piece aluminum center wing section to a fuse. These are the brackets I’ve come up with. They are shaped to keep the wing attach bolts on the centroid of the spars and aligned along a common longitudinal axis. Does anyone have any concerns with this arrangement? Am I going overboard worrying about alignment? Might it just be simpler/lighter to attach the brackets closer to the tops of the spars and forget about alignment (ala Mustang 2)?

I haven’t stressed the brackets, bolts, or fuse bulkheads yet. Brackets will be made from 4130 and I’m sure will end up lighter than what is shown. Also, appropriate doublers and other structure will be added as dictated by analysis.

Thanks,
Rob
