I noticed a while ago some discussion of the precise alignment of the
factory punched holes in the front spars. I have just got to this point
on my wings and have measured the holes. There is about 1/10 of an inch
slop between the two spars and between the two ends of the spars. This
will cause about 1/10 inch variation in the front wing attach point (I
think?). For most things, I think this amount of missalignment is not
important, but I am not so sure for this critical wing to fusealage joint.

So the question is, will I be able to adjust for this variation later? or
should I somehow ensure that the wing attach brackets end up in some
precise point, relative to the main spar of the wing and not the front
spar punched holes? Anybody have any thoughts, thanks.
