I took a break from the rudder to work on the elevator. Since I’m waiting on some elevator components to be delivered, I went back to working on the rudder today.
I got started by dimpling the #30 holes that will be used to secure the upper rudder tip.
I match drilled the rudder counterbalance weight to the mating rib. 
After drilling the lead, I countersunk the part. This lead is like cutting through clay. 
I match drilled the stiffeners and nut plates to the rudder spar.
I got to use my new vise-grip dimples to dimple the top rudder rib.
Here’s some of the parts getting primed.
I countersunk both sides of the rudder trailing edge. 
I riveted the spar doubler and nut plates.
Lastly, I riveted the counterbalance rib to the spar and riveted the counterbalance skin to the skeleton.
