I placed the wings on the rolling cart I used to move the plane around in my workshop. I needed to add some padding including rolled up rugs to get the wings high enough. They easily mated with the spar and using 4 guide pins I created from 3/8 bolts I temporarily attached the wings. I then attached the flaps and filed them on their inbd sides so they would not contact the fuselage. I then formed the lower fairing around the leading edge of the wing. I needed to grind away some of the inbd metal of the fairing so it would not touch the fuselage.
