Drilled (pilot, and final) Rt Wing Landing Light mount-to-leading edge skin. Deburred and Cortec'd LL mount.
Drilled (#40-->#30-->#20) final leading edge skin-to-main spar.

On the Landing Light mount, the rib feeler that I made for the left wing came in handy again. I have a picture of it included. Set the dept of how far you want, (mm) into flange from edge of rib on the jig. Then insert jig (the wing skin goes between the 2 tabs of the jig) over the skin until the side with the upturned end comes to rest against the rib. On the other size of the jig, draw a line at the outer edge. That line is the center of the flange on the back of the rib that the other side is up against.
