Full day today. I deburred and edge finished the aft skins, then prepped and primed. On the skins, I'm only priming a strip along the rivet lines where they mate up to a bulkhead or J channel or whatever. It's all alclad, so I don't feel the need to add the extra weight back there for no return. Sounds good in theory, but it really takes a long time to cut strips out of that blue vinyl with a soldering iron. For the skins, it was probably a couple of hours to do both sides, but it will be worth it to not have overspray all over the place. RJ hung out in the garage for a while and snapped a pix of me rocking my vinyl gloves. Then I started dimpling everything. Got all the skins and most of the bulkheads dimpled before I ran out of steam. There is an ellipse cut out of the aft end of these skins where the rudder cables eventually go through. Next to these cutouts, there is a pilot hole. I did some reading ahead and discovered on a later drawing (was it drawing 27?) that this gets a #8 flush screw thru it to mount an adel clamp inside to secure the rudder cable sleeve. I couldn't find anywhere that it tells you to drill and dimple this hole, but it seemed like it would be a real hassle to do it after these skins are all riveted on, so since I was set up for skin dimpling I went ahead and did them now. Will plan to finish dimpling and start putting all this stuff back together next time.
