I continued where I left off on the top spar.  This is a pain in the butt. Here you can see my flashlight illuminating the rivets already completed. 

After I finished the top of the spar, it was time to rivet the tops of the nose ribs. And the main ribs. 

Then it was time to move on to the bottom. I dip each pop rivet in primer prior to riveting the counterweight pipe.  Additionally, I fixed Mike’s pneumatic pop rivet tool.  It works pretty well, but boy does it leak oil.

A few pictures of the final product.  Ailerons are complete!  There isn’t a lot left to do on the wings!
