Flaps
The flaps are built like a mini-wing. There is a main spar that ribs attach too that are covered by a top and bottom skin. The rear spar of the flap is formed into the bottom skin and riveted to the back of each of the ribs. The top skin has the trailing edge bend in it and it overlaps the bottom skin where the rear spar is formed. It also protudes forward as a gap seal between the flap and the top wing skin.

Riveted the actuator brackets onto both flap spars and inboard ribs. Started riveting the left flap together.

Detail of the little shim that I had to put behind each flap rib to get the spacing just right.

This is what the bottom of the left flap looked like when I gave up for the evening.

Photo of the actuator brackets riveted to a rib and a spar.

February 11, 2002 - 2.5 hours
Finished riveting the left flap together.

This is a bad picture meant to show how I cut off three of the hinge rings to allow for a two piece hinge pin istallation. I'll try to get a better picture later.
