Assembled left wing main structure

October 18, 2010 – I finished riveting the main ribs to the left wing main spar, then I attached the aft spar.

When the ribs were attached to the main spar, I set the wing up on the spar, clecoed the aft spar in place, and taped off the rivet holes that other items will attach to.

I was able to use the squeezer on most of the rivets through the aft spar, but it wouldn’t squeeze the rivets at the inboard end because that material has several layers and is thick. So I shot those rivets. I also was working alone, and wasn’t comfortable using an offset rivet set by myself, so I shot the rivets with the manufactured heads going in through the thicker material. Not ideal, but I didn’t have any problems with the thinner rib material not seating.

The left wing main structure is now complete. I’ll hang it on the stand, and start deburring and prepping the right wing main ribs for paint.
