Brief Description:  Right Flap

Tonight I set the right flap up on my known flat work surface (an old heavy desk in our sun room) and riveted the main spar to the ribs, lower skin, and hinge. I pulled the spar to rib rivets first, according to the instructions, then riveted the bottom flange to the bottom skin and hinge, as I could use my hand squeezer on those in place in the sun room. Because of the hinge barrels, I needed to use my longeron yoke. Because of interference between the yoke and top skin, I had turn the yoke at an angle, which in turn required an adjacent cleco to be removed to set each rivet.

For the top side of the spar to skin, I turned the flap over, re-weighted it, and clecoed every other hole. The flap stayed flat when the weight was removed so I could take into the shop and shoot and buck this row of rivets. I then shot and bucked the 5 #4 rivets that connect the FL-706-A and B reinforcement plate and and angle. I then squeezed all but the aftmost rivets in the outboard rib. I finished up the evening by setting the four MK-319-BS rivets closest to the trailing edge of the inboard rib.

I'll get the last two rivets on the outboard rib tomorrow, as it got a bit late to run the rivet gun tonight.
