Brief Description: Drill the oposite rib access panel and match drill
Used the Fly-cutter to drill the oposite rib access panel. Fly-cutter worked great for such a large hole. Debured the access opening and doubler. Clamped the doubler to the rib match drililed the platenut screw holes and the rivet holes for the plate nuts. debur and dimpled the assess plate and counter sunk the doubler plate. I stayed with one rib to make sure everything fits correct.
