I am not sure if I am following every ones description correctly. But it sounded like the builder was gluing the bottom of the shear web onto the top of the bottom spar, is that why he said it was not vertical ? If I remember correctly the shear web should be on the backs of both top and bottom spars? Its been a long LONG time since I built this kit. Thats usually how its done. it was a litte hard to follow exactly what he was doing...
