Continuing with the wingtip preparations…
This shows the #4 nutplates for the navigation and strobes being riveted into place. I used stainless steel and countersunk Cherry nutplate rivets, which are expressly designed for the purpose. A standard hand riveter can be used, no need for the specialized and expensive Cherry puller(s).
A #4 screw fastens the bracket which will hold the nav/strobe housing.
Here the nav/strobe housing is shown in final configuration.
Here are the nutplate insertions (outside and inside) for holding the lenses in place. Next up is final AwlFair application, sanding and priming.
