This session involved clecoing together all of the parts of the vertical stablizer to make sure they are all fitting properly. Once together, I could use my reamer to final drill all of the holes to their final matched dimensions. Once all final drilled, I disassembled the parts again and started deburring all of the holes and edges. The heavy doubler fork I took to the benchtop grinder to smooth the edges on the Scotch-Brite wheel, though the interior edges I had to use a hand-file and sandpaper to access. Then I started scuffing a few of the parts with Scotch-Brite pads.

What's next? Finish scuffing all parts, then dimple and countersink, and prime the parts.
