Today I kept working on the cowling. I marked the left door for the holes that will become the quarter turn fasteners, and drilled the right door for it’s hinge. This allowed me to position the right bottom channel, and drill small holes for the quarter-turn fasteners on that side. I’m using four per side, and only on the bottom. I should add that I’m only drilling these holes as pilot holes for now. I’ll wait until the last possible moment to drill them to final size, and hopefully that will be after the boot cowl is riveted in place.
