Does anyone have a discarded spar splice fixture used as a jig to splice the spars? I have reason to believe that mine is improperly drilled. When I insert the two inboard alignment pins, the spars fit nicely. However, when I attempt to insert the outboard pins (to level the wings), the predrilled holes are about 3/8" too far inboard to align with the predrilled holes in the spar. What am I doing wrong?
