Wingtips Complete
Finished up both wingtips. Needed to install stiffening ribs that fit adjacent the ailerons Careful sanding on both tips yielded a straight, parallel 3/16" gap next to the aileron which was the minimum spec. I deviated from the plans by using all MK-319 pulled rivets instead of just the rearmost 6 rivets per plans. It sped the install up and once filled and painted won't be noticeable. After the rib install, I moved on to the position lights. I again deviated from plans by installing an aluminum doubler on the back side of the fiberglass. The doubler was designed by CAD by my building buddy Craig back in AZ for his RV-14 build. The nutplates allow removal of the light without removing the entire wing tip. The only item left is sanding approximately 1/4" off the back edge of the wingtips to be flush with the ailerons. I'm going to hold off on that part for now. The wings are now completely done, so I can turn my attention back to the fuselage. There are some items to complete before I can finally get the wings mounted.

Initial fitment of the rib. I tied a string to it so I could easily retrieve it if dropped.

Rib drilled and clecoed in position.

The rib primed and riveted in.

Paper template used to orient position light.

I used the aluminum doubler as a drilling jig.

Doubler installed after countersinking and nutplates.

Exterior of wingtip after doubler riveted in. I sanded the irregular seams in the fiberglass to give a nice flush surface.

Position light wiring harness completed.

Installed position light under its clear cover.
