The rear aileron ribs were installed with clecos. I had to countersink the two holes in the spar so flat head rivets could be installed.
Rivets were installed along the top of the of the skin. I used the squeezer for all the holes except the aft 2. I’ll have to get in there with a bucking bar. 
To ensure the aileron is flat during assembly, I weighed down the trailing edge. 
Rivets were installed along the bottom surface of the forward ribs. 
I closed out the bottom side of the aileron using blind rivets. 
The final product!
My two ailerons. Time to take on the fuel tanks.
