Empennage, Horizontal Stabilizer (Part 2)

Well, I took a few days off from working on the airplane to go to Sun-N-Fun 2017 at Lakeland Linder Regional Airport in Lakeland, Florida.  I flew over Friday morning with my buddy Jeff in a friend of our's RV-7.  Several additional friend's and airplanes meet up with us at the airport and we camped with our airplanes.  Incredible weather and great friends!!!!!  While at the show, I got to eyeball several RV's and visit the Van's tent to see Mitch's RV-14A.  We all packed up and sadly left this morning.  When is Airventure again?????
 
After being exposed to ALL the motivation, I eagerly started working on the plane this afternoon.  I resumed work where I left off on the Horizontal Stabilizer.  I got started by riveting the HS-906 Rear Spar Doubler to the HS-00903-1 Rear Spar with AN470AD4-6 rivets.  As the plans directed, I marked the 12 holes (clecos actually) that do not recieve rivets at this time.  You can also see the two AN426AD4-6 rivets in the center of the Spar.  
 
The HS-912 Hinge Brackets (x8) were then riveted to the Spar using AN470AD4-5 rivets.  Here is one of the finished products.....
 
The VA-146 Flange Bearing was then clecoed between the two HS-911 Inboard Hinge Brackets.   The holes common to all the parts were Final-Drilled to #30, the Flanges were Final-Drilled to #12, and then all the parts were disassembled and deburred.  The Brackets were also scuffed in preparation for painting in the future. 
 
After preparing the three pieces, they were riveted together using AN470AD4-6 rivets.  Here is the finished product.....
 
.....and installed on the Rear Spar with AN3-5A bolts, NAS1149F0363P washers, and MS21042-3 nuts.  The Self Locking Nuts were torqued to 28 in lbs as indicated in the plans.
