Weather was almost pleasant today.  Low 40s and sunny.  Got out to the airport around 11AM.  Back to the Elevator nut.  I tried the new 75 degree wrench and the standard 7/16” wrench grinded down even more.   Here's my modified 7/16" wrench.

 

 
And my new 75 degree 7/16" wrench.  The 75 degree wrench wouldn’t even fit on the nut!  I tried filing the inside surfaces but no go.  I was able to grind it down some with the Dremel which is all I had in the hangar.  I also cut the aft tip off on both wrenches.  With these changes I was able to turn the nut – just barely. 

 
 

So I got the nut tight.   I caused this problem myself -- when I drilled the elevator horn, I drilled the top hole a little too close to the horn flange.  Rookie mistake. 

With #4 1” long screws, I was able to get the Nav/Strobe light mounted on the rudder.  It took a little effort to shove the wires into the rudder bottom tip.  Tested the lights: worked 4.0.  Check another item off the list. 

 
 
 
 

I used this mil-spec RTV to glue the NACA vents to the inside of the fuselage.
 
I let it dry overnight with the clecoes on. 
 
 

I finished up the autopilot.  Safety-wired the three bolt heads on the servo.  Screwed down the wiring D-connector.  Secured the wire bundle with tie-wraps.  Tightened the jam nuts on the servo-push-rod.  Used loc-tight on the jam nuts and torque seal on everything. Keep in mind I did all of this laying on my back underneath the wing!  Tested: worked 4.0.
