I have a question about an upcoming step. I'm thinking about how these holes will be countersunk or dimpled. In this first pic, do these holes get dimpled or countersunk? And how about the holes on the bottom of the spar flanges?
For the holes in the pic below, dimpled or countersunk? I would think the holes with the black arrows would be dimpled, but how about the holes with the red arrows? That area of the bulkhead has a doubler behind it and I wouldn't think I'd be able to dimple two layers of aluminum? Or maybe it's easy and that's how it's done.
I just want to make sure I don't do anything stupid and have to order new center spars or bulkheads!! Thanks!
