Wing Tip

Posted on May 14, 2025June 3, 2025 by Neal

Last night I fitted the left wing tip’s rib. This involved locating some holes on the rib and on the fiberglass, so that the web of the rib is flush with the edge of the wingtip.

I miscalculated one hole, and needed to fill it once I was done with locating all of the other holes. holes are then countersunk, and the rib deburred and primed.

Tonight I riveted the rib into position. This required the rivet gun, as the flange of the rib is facing inside the wingtip (i.e. outboard). The riveting was quick and easy.

Rib taped into position, and drilling underway.

Once the rib was installed, the wing tip was completed, except for trimming the rear edge. I installed it and marked the line where it will need to be sanded back

Wing tip nut plates

Tonight I installed the wingtip nutplates on the left wing. I had to order a few extra from aircraft spruce the other day, because I was 5 short of the number I needed.

I found one nut plate where the holes weren’t quite aligned, so I filled one of the holes and will re-drill, countersink, and rivet the nutplate on tomorrow. Otherwise I finished the task.
