Riveted the 808/9 bulkheads together. The 807 paint was still wet (see yesterday's entry). Riveted the 810 together. I went to rivet the 809 and discovered that while I had match drilled #30, I had used too large dimple dies so the holes in the 809 fit -5 rivets now. I had to order flush -5 rivets from A-S to rivet the bulkhead together.
