This morning I riveted all the stiffeners to the skins, even got a little help from mom on a few of the rivets. In the end all of them came out perfectly.  

 
Next I began on the rudder skeleton. It’s a much more involved structure than the stabs were.  

 
Here you can see the counter-balance skin clecoed onto the tip rib and the counter-balance rib. Once everything was clecoed I match drilled everything together. 

  And here is the rudder all drilled together. 

 I then disassembled everything and deburred all the holes.  

 I also countersunk the lead counter-balance weight for the dimples and screws that will hold this to the rib.
