The vertical stabilizer skin has 206 holes that need to be drilled to final size plus 4 more that need to be match-drilled into the forward flange areas of the tip and nose ribs. The holes in the skin are already final size, which made the final-size drilling of the substructure go quickly. When all the drilling was complete, everything gets disassembled to enable deburring of the holes and edges and prep for primer. I deburred the holes in the skin and decided to call it a day.
I will continue deburring holes in the ribs and spars tomorrow, but the edges will have to wait a few days until I get a couple more deburring accessories. It's also time to make some decisions about priming – like where I'm going to do it!
