Over the last couple days I got the stiffeners riveted to the other rudder skin, the top rib halves riveted to each skin, and the bottom rib with the rudder horn riveted to one skin. I did skip a couple rivets on the bottom rib because it got too tight to get a squeezer or bucking bar in there so I have to research how to set them. I also got the shear clips riveted to the stiffeners using blind rivets. Blind rivets work a little bit differently than the other rivets I’ve used so far. Blind rivets are like hollow cylinders with a rod that stick through it with a ball on the end. You stick the rivet into the hole and then use a tool to pull the rod which then deforms the bottom of the rivet which creates the shop head which holds everything in place. Once the rivet is fully set the rod snaps off and you’re all finished.
