Work continued on the ribs of the rear fuselage.
I positioned the parts of rib 5 in place with the jig. The 2 corner brackets are a tight fit and to prevent the primer being scraped away a added a bit of Ardrox there:
Next I prepared and primed rib assembly 4, the primer can cure overnight.
Unfortunately there is a blocking issue here, the 2 corner brackets are labeled incorrectly, I have 2 similar parts but one is labeled “right” and the other “left”. Annoying this, because I have to wait for a new bracket 🙁
