My alternative for a fuselage lifting point. The main reason I did this is to have a removable picking point so nothing is sticking up above the wing fairing. It's a nice simple design that uses a forged 3/8ths eye (US made, not Chicom crap), a Grade 8 nut that is captured on the bottom using a Home Depot socket. That way the nut doesn't lose strength after welding and I don't have to rely on hand-cut threads. I annealed the 9/16ths socket so I could drill a hole just a bit bigger than 3/8ths where the drive would fit. The bracket is made from .071 4130 plate because that's what I had the most of on the shelf. I'll probably go with .080 for the final copy. What isn't shown in the pics is a hole that I will drill at the bottom edge of the socket for a small loop of safety wire to keep the nut from falling out. I’ll send it out for load testing.
