Started drilling Landing Light top rivet points. Seemed to go well. Then remeasured and drilled some of the bottom rivet points. Couldn't get the flange forward enough. It looks like I might have to redrill further aft. This sucks because I had measured, and remeasured from the spar. The skin pilot holes (that I drilled), when lined up as good as I could, looked to be almost on the rib front bend.
Going to bed to step away from it for a while to think.
