As a result of mating the spars on Sunday, I just wasn't pleased with the left spar's outer wing attach block. The mating hole was straight, but not perpendicular. Tried removing the attach blocks to ream them out on the drillpress (went 1/64" oversize) to try and get them a bit better.
After spending some time, I realized that I'd still have doubts, especially during the up-drill to 3/8" after the wings are complete. Additionally, Kerry mentioned that at the angle of the hole, there was a possibility that the AN6 wing attach bolt might interfere with the fuselage wing attach angles.
