Got bored a little later on so headed back out to the workshop. I was just going to 'take a quick look at a couple of things'. Well, we all know how that usually turns out. Anyway, I ran a couple of plumb lines and got the wing skeleton all level and straight. Then I clamped the rear spar at both ends so that a plumb line ran down the center of the rivet holes in both endmost rib flanges. This will wing be true as (famous last words!).Of course, I had to make some extra brackets and bits, and so hence the time. Finally, I worked out which holes on the rear spar get rivets and which don't, then cleco'd every hole anywhere that attaches a rib to either spar (including those on the spar flanges where the skin will get attached). My method is; every hole with a cleco underneath gets a rivet; those where the cleco has been put in from the top do not (but the cleco still helps hold everything in proper alignment - easy!!).Actually, I noted that some of the spar flange holes do not line up with the rib flanges. Either the flanges have got bent, or the 'true' alignment of the skeleton is such that the 'mis-aligned' match-drilled flanges no longer match. Its not a problem; the rib flanges are 'flexible' and I'll just have to make an extra effort when match drilling the skins not to elongate the holes; worry not, I have a plan!!
