Mike, I don't know how you were able to do that, my wing just came together like a jigsaw puzzle. I built the first half over the plan and the other with the plan hanging on the wall. I built them the same way as boths halves are identical. I did align everything by eyesight at crucial points such as before glueing the top spar, TE/LE, shear webs and sheeting. Such a tapered symmetrical wing should have a jig to be guaranteed straight but I've always relied on eyesight to get it even, and this looks to be the straightest wing I've built so far.
