Did alittle adjustment to the sweep. My dimensions were good, but the plumb bobs should just alittle fwd sweep (3/16") on both wings. Once that was done I checked and re-checked and re-checked all of the critical dimensions. I then layed out my edge distance lines on the rear spar carry through.
Once that was done and re-checked my marks. I again re-checked the incidence and sweep.
I then pilot-drilled #30 the left wing. I put a cleco in the hole and re-checked everything. I then pilot drilled the right wing and cleco'd. Everything looks good.
Ran out of time so I'll have to open up the hole and final ream to 5/16 next session.
Have to stay inside the narrow rectangle. The horizontal lines taper following the carrythrough shape
