I actually didn't do 1.6 all together, it was more like in spurts with all the stuff going on around the house. I'm glad I got a little bit done at least. Finsihed counter-sinking both inpection cover reinforcment rings and started riveting the nut plates on to the assembly (the rivet goes through the rib and attached to the reinforcement ring.) I'm 3/4 of the way to being finished with the nutplates and then it's on to something else.
Riveting the nutplates - not used a cleco in one ear of the nut plate and put a screw in for alignment
