I worked on installing the nutplates to the left wingtip today. I got all the nutplates drilled, countersunk, and riveted. The only issue I ran in to was the countersinking. Because of the lip on the wingtip I couldn't use the machine countersink cage and had to do it by hand with the deburring tool. All the countersinks came out fine. They just aren't quite as precise as with the cage.
