Just starting the wings...
How does one mount the outboard end of the spar to the jig? Dwg 12A, detail B shows an angle mount but I cannot understand how that would secure the spar. Do you have to attach the last rib and bolt onto that? What exactly on the rib/spar does the 3/16 bolt attach to? How do you secure the spar to the jig without interfering with the last rib?
