Brief Description: Flap - Drill ribs to spar, make shims.
First building task is to drill to #30 the ribs to the main spar. Interesting the holes on the internal ribs and spar are #40 pilot holes.
Shims made as per plans. No biggie here. The top skin wraps around the trailing edge to the bottom skin. The shims live on the bottom under the top skin. It makes sence once you see the plans.
