@ Kevin : welcome back
but now it starts ...
Start with Part 1, the ribs I stick to 0.9 mm Finn cardboard ... the first cylinder is standing, cut the ribs on line, fits perfectly
Fuselage parts 1 + 2 connected, very accurately fitting ... I cut the reinforced frames first roughly, then I divide the edge into segments.
Finally cut out with the cutter around.
Yours sincerely
Kurt
