Brief Description: Drilled aft Spar for Top Skin & Gap Seal
1. Today I stopped riveting and began drilling the top skin to aft spar. I started in the middle and worked outward in both directions. I Clecoed the #1 root rib in place before drilling the skin. I think not having it in place would shift the skin a little. 2. Once all holes were drilled I removed all the Clecoes in the last 5 rows so I could lift the skin to debur the new holes. I used a twist deburring tool on bottom lip of spar and top of skin. other surfaces just got a pass with Scotch Brite. All came out good.
