Match drilled 4 Main Ribs (2 W-1210R and 2 W-1210-L) using the W-1216B Hinge Rib and W-1216 Hinge Bracket Assembly. Deburred the drilled holes. Also sanded/deburred the trimmed forward web of the Main Ribs. I still need to debur the lightening holes and the flanges of many Main Ribs. The ribs have a lot of burrs and they need a lot of filing, grinding, deburring and sanding to make the edges smooth. Most of the work in Sections 14 and 15 was deburring.
