Today I deburred the upper wing skin and began to debur the stringers. I also trimmed a bit off the root end of the stringers. Although I drilled my first hole 3/8 " in from the end, I began to assemble/match drill them with the first set of holes for the root rib. I later noticed I needed to set them in another hole to provide clearance for the root rib. Easy enough since they were long enough and hung out the other end. I will however, need to trim off the two already prosealed on the bottom tank skin. I'll use a small cutoff wheel on the dremel and get them close enough to break off without damaging the skin.
