Brief Description: Flaps - Squeeze rib and pulled rib/spar rivets
Next I squeezed the -7 length rivets through the inboard rib doublers. And put three pulled rivets on the spar to rib-flange on the outboard rib. I tried squeezing rivets here and then also tried pounding rivets here but I didn't like the result so I just used pulled rivets per drawing. The flaps are almost done.
