Wow -- an incredibly productive day today! I chalk this up to the fact that I've done today's projects before, on the left wing.
I began by marking, pilot-drilling, and enlarging the conduit holes in each wing rib to 3/4". Then I deburred the holes, masked them off, and shot primer around each hole. After it dried, I cut about 11 feet of conduit and installed it in all but the four inboard ribs. Total time elapsed on the conduit: 1.8 hours so far. (This was the same job that took over 7 hours of work the first time!)
Next, I prepped and taped the Duckworks landing light template to the wing, and marked the wing skin for cutting.
