After spending the morning and afternoon at MERFI (sorry, no pictures), I was able to spend a couple hours installing these seven nutplates. Yes, that's right...it took two hours to install seven nutplates. Sigh. I also used Brent's nutplate drilling jig to drill the center support angles for both the left and right sides. I should see him at the EAA Chapter 9 directors' meeting, so I'll return his jig at that time. Thanks for the loan!
