I continued work on the left aileron. The leading edge ribs were dimpled.

I countersunk the holes in the counterweight.
The dimple on the leading edge of the part was formed by using the counterweight as the female die. I used a mallet and my normal male die to create the dimples.
All aileron parts were primed.

I used a blind rivet to attach the leading edge rib to the counterweight.
The remaining leading edge components were cleccoed together.
