Didn't do much again, but every little helps. I drilled the two outboard bay ribs for the nutplates that hold the leading edge light bracket in place, then disassembled the leading edge. Also drilled the W-423 joint plate for the nutplates. The whole leading edge and light components can all be deburred and edge finished next week ready for priming, maybe on Friday: I'm thinking of taking the day off work to do it, since that weekend there'll be half price skydiving and I don't want to miss that!! :-)
