Rudder Spar Assembly Part 3

Attached the rudder horn to the spar today...

...and riveted it on.  That was easy.

Shop side of the rivets look good.

And primed over the rivets.

Don't forget to remove the blue film from the inside of the rudder skin:

and cut the little tab thingy off.  Used a hack saw but in retrospect I should have used the metal snips.  What was I thinking?

Deburred all holes and edges then cleco'd the skin onto the rudder skeleton:

Using about 170 pop-rivets I fastened the rudder skin to the ribs and spar and voila!  A finished airplane rudder!  As with the vertical stabilizer, I'm keeping the blue film on for now to protect the alclad from scratches.  A productive weekend!

Next up will be the anti-servo tab for the horizontal stabilator, or simply "stabilator".  The AST is a vertical trim tab that also induces feedback resistance in flight to give a balanced feel at the control stick.  The stabilator is also dual-function in that it combines the functions of the horizontal stabilizer and the elevator in one part.
