August 26, 2010 – It’s been a while since I’ve been able to do a good day’s work, so I got it out of my system.
Countersinking the holes for the tank attach nutplates was a bit intimidating, and I had a rough hole or two to get started, but once I got into it, the job kinda flowed on. After figuring out the settings for the countersinks, I drilled a plate with some holes to accept the pilot of the countersink to prevent chatter, then I drilled away.
Everything looks pretty good.
I then installed the nutplates for the tanks and for the access panels on the bottom of the wings, and the 1/4″ nutplates for the center section.
