Some steps take just a few hours and have a very rewarding result:
First I riveted the 5 inside longerons to the bottom skin (not the side longerons!):
Attachment of the rear rib assembly:
I didn’t rivet the first hole, I think they are rivetted when the center fuselage get attached:
And I didn’t rivet these rivets because rib 4 slides in between:
Another location that I didn’t rivet (because the manual explicitly states so):
From some scrap wood (like the wooded crates from TAF) I made a RF cradle on casters:
I temporary attached the ribs (except rib 3 due to the missing parts):
Looks like the rear of an airplane 🙂
