Productive day - Hillary helped for a while, but most of time I was riveted by myself. Clearly a completed piece with several different sizes and types of rivets.
Overall, very pleased with outcome. One rivet needed to be drilled out and went fine. I used larger rivets than the manual called for for four of the rivets holding the F-1211D brackets - I think there is an error in the manual as longer rivets were needed to properly attach the brackets to the bulkhead.
