Brief Description: Drilled and Riveted Bottom Skin--Left Wing
Drilled the skin and top flange on the aft spar. I vacuumed the drill shavings from the inside of the wing. After deburing all the new holes with a twistie tool (drill bit), I lifted the skin and cleaned shavings from between the skin and spar. I tried to debur under the spar top flange but it was impossible to get to most of it. The burrs were minimal and should never be an issue. I finished riveting the bittom skin to the left wing.
