Fit Ribs to Spars

Hey, it actually looks like a wing! I had to file the slots in the ribs slightly in order to get them to slide over the spars smoothly. Many of the ribs had to be filed in the same place, which means one of my jigs was off slightly. Also, I weighed each of my spars to see if I had a slightly heavier one. It turns out that the left spar set is about 1/2 pound heavier than the right set. So, when choosing the ribs to put on the left wing, I picked out the lightest ones. It turns out that there's not much difference between the ribs, and the stack of left ribs was only about 3 ounces lighter than the right stack, which means a net difference of about 5 ounces between the left and right wings so far. I think I can live with that! (By the way, my front and rear spars weigh about 16 pounds total, and the ribs weigh about 8 ounces each, so, at the moment anyway, each wing weighs about 24 pounds, total. Also, the ribs are not glued in this picture.
I just thought I'd see what the wing was going to look like.)

Total Time: 8.0 hrs.
