I finished fitting the rear spar carry thru. I'm ready to drill the main spar angles but need to find a couple longer drill bits first. I worked on the wing tips. I'm using the Kunzleman nav/strobes and they just have a flekey self tapping screw to hold them on. That's not gonna work with fiberglass. So I got an extra set of the adapters and on each wing tip put the other one behind it so I'd have a flat surface on the other side. Then I'll put nut plates on them and use long 6-32 screws.
