I'm at a point in the Rudder construction that I need the assistance of a second set of hands. So, in order to maintain forward momentum, I started on the Horizontal Stabilizer.
Lots of work was accomplished today, but as I mentioned in previous posts, sometimes it doesn't appear that way. I started by deburring the HS-00903-1 Rear Spar and HS-906 Rear Spar Doubler and then clecoing the two pieces together.
Once the two pieces were clecoed together, I final-drilled #30 all the 1/8 holes common to the Spar and Spar Doubler, four holes were match-drilled #30, and two holes were machine countersunk to accept AN426AD4 flush rivets. I used the Threaded Micro Stop Countersink and a #30 Countersink Cutter to prepare the last two holes.
The HS-912 Hinge Brackets were clecoed into place on the Rear Spar as shown below. There are a total of five Hinge Brackets that attach to the Rear Spar.....four of the Brackets (HS-912) are attached now and the fifth Bracket (HS-911) will be attached later in the plans. Once clecoed into place, they were final-drilled #30 to the Rear Spar. All four of the Hinge Brackets and the Rear Spar Doubler were then removed from the Rear Spar. The single 3/16 hole in each of the Hinge Brackets were final-drilled #12. NOW, all the prepared holes needed to be deburred.....yeah!
Work on the Horizontal Stabilizer.
