I riveted the flap brace to the wing, using MSP-42 blind rivets everywhere except the inboard three rivets, which were heavy-duty flush Monel Cherry rivets. (This is a Quickbuild procedure. Standard builders use different rivets here.)
Next, I riveted the flap hinge, brace, and wing skin together using MS1097AD4-4 rivets (1/8" Oops rivets). See the 9 October 07 entry for an explanation. The hinge looks great, and you can't tell I made a drilling mistake. Sweet!
I made a test attachment of the flap to the wing. It went on just like the left one. I did fight a bit with the curved top skin of the flap, however, so I curled it by hand, taped it in that position, and left it overnight to see if I can persuade it into the right shape.
