I worked on the side cowling supports this afternoon. It was nice enough to actually open the hangar door and let the warmth in!
The idea with these is to rivet the bottom onto the bottom cowling, then add the camlocs at the top. As usual, I overthink everything and it took me longer to figure out where to start and end them then it did to make them. I wanted the spacing of the camlocs to be similar to the sides. (I am within 1/8 of an inch.) I also ended up putting the rivets on the bottom 1 inch apart. (Some people put them farther apart... but I want to error on the side of too many.)
