Empennage

The drill bits that I ordered over the weekend came in the mail today. I was able to go back and drill the attach holes for the HS-708 to the #19 size. I was also able to use the #12 size to drill the bolt holes that will attach the HS-411 bearing assembly to the spar. That finished up the Rear Spar Assembly so I moved on to the Front Spar Assembly.

I took the two HS-702 front spar channels and put them end to end. Then I cleco'd the HS-710 and HS-714 reinforcement angle to them. Then I drilled the holes inboard of the HS-404 and HS-405 rib attach points. When that was done I took HS-710 and HS-714 off and tapered the ends as per the Taper Detail in the drawing.
