Today I countersunk the cowl flap and riveted together the flap unit. Everything was straightforward except one rivet that was repeatedly problematic. The rivet tipped 3 times, and each time I removed it, before I was finally able to set it. Even the last time I set the rivet it tipped over, but I decided it was good enough.
