Solo Wing installation
You can do it by yourself if you wish.
I used several hardware store bolts matching the four main spar bolts. Grind off the threads and grind a bullet nose on the bolt. Chuck the bolt in a drill press and polish the cheap bolt to a smooth slip fit through the spar holes. you can test the fit with the wing apart. Lub lightly and slip through both the wing and center section holes. Make two of these for each wing for temporary alignment.
I used four saw horses ( Mostly for drop protection) an engine hoist, tie down straps and some 2x4 s.
If you are interested I can send photos. PM me.
