This is really just more of the finishing process. I want screw in tip lights (Aveo) with real nutplates and embedded as deeply as possible to reduce their footprint. I had already made provision for this when I built the wings by having an oversized indented area for the lights. I did this job along side a lot of other refinishing over many days.

First up was making a set of nutplates using some scrap aluminium. I did alodine them for good adhesion.

The dremel came out and I went for flush inserts.

After floxing them in I was going to add a ply of glass over the top. Given these are bearing just a tiny load and that they felt very secure, I omitted the glass.

While filling the winglets I did the usual tape release thing so I could knock off a couple of tenths of an inch in light fitting height.

Here’s part way through the fill. You can see the filler is also now helping to hold the nutplates in place. The edges need some work still. You get the idea.
