Started assembling the right flap this morning. I cleco'd the skeleton together and then the skins wit the spar installed to make sure everything was aligned properly. I then removed the spar and started riveting the bottom skins together (where the top skin comes around and rivets to the bottom skins about 3 inches from the trailing edge). I got it all riveted up when I ran outta time.
