I had to buy a new Unibit to drill the holes for the wiring conduit that I bought from Van's. My largest Unibit only went up to 3/4 and I needed a 13/16 hole. Once I tracked down the right Unibit, I enlarged the rear tooling holes in each of the ribs for the left wing. These were then deburred. The ribs are now ready to be primed.
Wiring Conduit Holes drilled next to trailing edge of each rib
