Wings: Ailerons. Parts and stiffeners riveted.

Various parts and the stiffeners have been riveted together on the ailerons.  

The rivets for the stiffeners were inserted into their holes then taped into place for back riveting.  This let me run through the back riveting process in minutes.

The skins were then stacked on each other whilst I riveted together the other various parts via squeezing.

Returning to the skins, the stiffeners were then back riveted quickly.

And now the ailerons wait for the remaining work whilst I pay attention to the flaps.
