This is where loads of fun can be had. To the naked eye, adding a few stringers should be a 10 min job. Yes, sure, but if I can stretch it for a few days? First I added the round formers from firewall aft. They all have the same radius as the firewall, so that makes life a bit easier.
Anyway, a good day was had, and I think I have the process worked out now. As always, let the pictures tell the story.
The bending contraption, borrowed from Thomas 😉 Difficult to see, I try to show the false formers here. try gluing a tiny bit of metal to a 4 mm tube, when you only have 2 hands. (Note to self: don’t forget to fix the inner corner on the opposite site. )the end result, stringer #1 done. cockpit sidetail side, the stringers are fixed with a pop-rivet. They were also alu from what I can find. I like this better!Even Paolo’s brazing look a mess until cleaned up, so I don’t feel too bad. one side done..nice job, even if I have to say so myself
