After a bit of a break from planebuilding over the weekend, I resumed work today by finishing dimpling the left flap spar and all of the ribs. I then started hand squeezing rivets into the flap hinge brackets and nose rib assemblies. The hand squeezer still seems like my preferred riveter for things when I can use it. Then I started using the air rivet gun to attach the ribs and brackets to the left flap spar, however I only got about half-way through this part before I had to call it a night because it was getting late.
