Empennage

Horiz Stab (3.5 hrs)

Sect 8-11 continued Step 3:  Riveted 4 Nose Ribs into skins, 2 per side.    Challenging and awkward due to reach and positioning -- especially when needing to switch using left hand for some of the rivets.   My wife joined me to help hold skins "tight" to ribs for some locations...she was not only helpful but offered encouragement too.  (although she did slip in comment "Rosie the Riveter would've had this done already")

Step 4:  Insert Front Spar / Inspar Rib Ass'ly into skins.    Yeah !  fits great and aligns perfectly.  Cleco'd Top and Bottom, Left and Right...took nearly hour just to check engagement of each cleco, etc.

Pic to show alignment...straight through nearly 114 inches.

test fit Rear Spar

I also test fit the Rear Spar...not ready to add yet, but fits really well also.  Critical to orient top from bottom, too.
