Dimpling wing ribs
I riveted my main wing ribs to the main spar tonight. Now I'm getting ready to attach the rear spar to the main ribs. The order here is different than I'm used to per the instructions. The main wing ribs overlap the rear spar on the bottom side at one spot, and that will get dimpled. Should I dimple those spots before attaching the rear spar, or is it ok to dimple two layers of material at the same time with a squeezer? The plans call for a CS4-4 rivet here, which is a little odd. Hopefully this makes sense. I tried to attach a photo to help explain.
