Rear Spar and ribs, continued

September 10, 2010 – Nice day today. I assembled the rear spars and did the preliminary fit of the left wing ribs and spars on the stand.

These three pictures show the three areas of the rear spar with the doublers attached. The open holes are where other parts will attach later.

I then clecoed the main ribs to the fwd spar and then clecoed the aft spar in place.

Here’s the left wing as it sits right now.

Spar nutplates complete

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.
