I was attaching the top rib to the forward spar of the vertical stabiliser. The rivet I set bent over to the side. I decided I would drill it out and try again. The next one was no better so I drilled that one out as well! The next one was worse so I drilled that out as well. You know how the story goes but I?ve attached photos to illustrate.
My solutions:
1. Tidy up the oversize hole, debur it etc and leave it and drill another hole an appropriate distance inboard and set a good rivet. This is my preferred solution because it is relatively straight forward.
2. Drill out the hole to the appropriate size and install the next size rivet. It will be a large rivet and I don?t think I would have such a rivet to hand. That would mean I will have to source a big one and set it in the relatively thin metal. But I could probably do this.
3. Drill out the hole and install say an AN3 bolt. Extra weight and it probably looks as messy as a blank hole.
4. Create a sandwich with two pieces of aluminium on the top and bottom side of the join as per the attached diagram
It seems to me the strength in this structure comes mainly from the skin attached to the rib and spar and even a structural pulled rivet might do the trick. But can I please have your views.
