Today, Charlie Eubanks came over and checked all my rivets. He gave us a passing grade and didn't ask us to drill any out. This afternoon, I began preparing the other spar for riveting, deburring and cleaning edges on the main spar itself, and the W-502 doubler. In addition, i primed both. I should be able to finsih the other parts tomorrow, and begin riveting in the evening or Sunday afternoon.
