The picture shows the fuselage after todays session. It looks like some progress but no. I had lots of trouble riveting the tailcone, the skin that was difficult to form was also difficult to rivet.
I thinj the skin was not correctly bent and I had to drill out a few rivets, this enlarge some holes. I think my riveting technique was not very good, the part is difficult to rivet alone.
The result is that I decided to redo the tailcone completely because this part supports the empennage.
While waiting for the parts I have enough to work on (wings to finish, seats...)
