My buddy Andre stopped by today and helped me get started on the wing kit. The first thing you do is install a lot of platenuts. These will be the platenuts that receive the fuel tank screws and inspection cover screws. Here is Andre drilling one of the center holes for the platenuts.
Here you can see the countersinks for a couple of the platenuts. The center hole is countersunk for a #8 screw and the outer holes are countersunk for AD3 rivets.
Here is one completed row of countersinks. Instead of Van’s recommended method of countersinking. I used a long piece of 1/16″ aluminum angle clecoed below the spar flange. Way easier and more precise.
Here are both spars prepped for priming the exposed countersinks.
The battery in my digital scale died, so I broke out the NAPA 7220 self-etching primer.
After the primer dried, we installed all of the platenuts. This went surprisingly fast with two of us and we had them all installed in about an hour. Here you can see that the lower platenuts are countersunk for #8 screws and the upper platenuts are not countersunk for the #6 screws in the access plates.
