Deburring is complete, and all vertical stabilizer pieces have been scuffed prior to priming. Final preparation for priming will occur within 2 hours of actually applying the primer to minimize oxidation between cleaning and priming.

Dimpling the #40 holes in the flanges of the front and rear spars as well as the ribs is nearly complete. The two forward-most holes in the tip rib need a close-quarters dimple die to make the dimple. I have a dimple die set to be used with hand riviet (pop rivet) tool, but the nails that came with die set to be used as mandrels for the hand rivet tool are too long and too thick to use for these holes. I'll have to see if the hardware store has nails I can use as a replacement.
