Got some more accomplished today, worked far too long to the piece in the center photo, it goes back in the tail end. I misread the plans and put the wrong kind of rivets in three holes, had to drill them out. I happened to have my finger behind the rivet, and spattered blood pretty well when the drill sunk into my finger. Taking blood thinners and aspirin to keep my artery stents flowing, I bleed pretty dramatically. Blood on the plans will remind me not to do that again. Regardless, I got the tricky tailcone bulkhead all done.
