Installed wing inspection plates, wings finished - 3 hours

Last step was to complete the wing inspection plates. I had filed all the edges on the inspection plates down to clean the shear marks off, and then chamfered the edges to ensure a good fit with the radius corners of the skin. I ran each through the 3M wheel to finish the edges. I final drilled each screw hole on the drill press. Most important, I polished each hole with the dremel and fine grit sandpaper (lesson learned from the wing tank screw hole to ensure no cracks in the thick material when dimpling). The wings are now ready for storage.
