Below is a fitting for the upper wing center section on the R&D wing (I'm hoping it shows up... not quite sure how to attach images with the new set up yet). Anywho...

1. There is a hole in side "A".
2. The same hole needs to be in side "C".
3. Both the areas where the hole is on "A" and "C" are at about a 6 degree angle.
4. This fitting fits over the end of the spar to attched the wing panels.

I'll drill the hole on the one fitting...

My question... do I match drill these after I have the fitting welded together and slid over the spar of the wing panel? I think I do but I want to confirm with the group.

Is this making any sense ?
