Just killing time here doing some dimpling of the wing walk doublers. Update: Make sure you don't dimple all the holes along the inboard-most rib. Some of those holes get drilled #19 for wing fairing attach screws.

...and a wing skin.

It's hard to see, but above and to the right of the lightening hole is a #40 starter hole for where the conduit will go. I drilled one of these and then transfer drilled all the other ribs. I want all these conduit holes to be right in line so the conduit will be easy to slide in.

I did some priming yesterday (didn't get any pics of that) including the pitot mount. Since it had dried, I decided to rivet on the nutplates.
