Wing Ribs – Part 6

First, this update is a little late in being published.  Don’t worry, I have been making progress and should have more updates shortly.

With some work on the leading edges done, I moved back to the wing ribs to get my right wing ribs attached.  First I assembled the ribs on the spar, then started to mark and drill the holes for the conduit attachment pieces.

After moving the spar to the workbench for better access, I began to attach the tie-down bracket to the spar.  Only had to drill out a few rivets due this time before everything was perfectly attached. 🙂

Next I began to rivet on the ribs to the spar.  This is easy enough to do solo if you are careful.  As I got closer to the wing root I was limited on physical space.  Feel free to laugh as I squeeze around to get the last few rivets set.

With the rivets all attached, I then started to install the AN3 hardware attaching the ribs to those stepped spar doublers.  I’m not sure I got it on camera, but I basically put the hardware on just tight enough to hold at first.  I came back later with a torque wrench that could measure in the in-lb range needed to set the AN3 hardware to spec.  A little dab of torque seal to help mark what hardware got torqued and I’m all set.
