Re: Are these good enough?

Michael, thanks so much for posting this honest video and the information that goes with it. I'm sorry that you have encountered this setback. I am now certifiably terrified of my future spar rigging experience. That seems like a very small play that wouldn't even be perceptible if the wings were actually in the spar tunnel. You've shown a lot of diligence in detecting this small error.
How does a bolt play when inserted through your wing spars outside of the fuselage? I'd think if the wing spars themselves don't show play with each other, your option #2 would be the way to go.
Edit: I've read a lot recently about pre-drilling the spar attach angles all the way up to 3/8" before the rigging process. This isn't how the plans call for it. However if such small tolerances are necessary for the spar tunnel angles, I'm really starting to reconsider the method I'll use. The more time a drill bit spends between those angles, the more elongated the holes will get. It really seems like a very delicate balance between the play in the bolts and the rigging of the wings relative to the fuselage.
Did I mention I'm starting to lose sleep at night the closer I come to this?
