E-921 Gusset Drilling
Does anyone remember how they drilled the E-921 gussets on page 09-08 of the plants. If I try to drill from the inside into the forward spar, the other cleco holding the gussett is in the way, even with an angle drill. If I try to drill from the spar side, the root rib is in the way due to the angle.
I guess that I could just drill the spar holes without it being assembled.
