Received the replacement CCC-42 rivets yesterday. These replacement rivets still have a bit of a chisle point, but seem to have a slightly broader nub on the mandral. Installed the inboard leading edge CCC-42 rivets, and happily, not a single mandral broke "proud". Certainly worth the ~$14 to avoid the hassle of dealing with mandrals breaking proud.
This completes W12, Inboard Wing Panel Skinning.
Started working on the C04-03 flap and aileron fairings.
Updated the Drawing Tree, B03, checking off blocks I've completed. Getting pretty close to the second from the top row.
