Horizontal Stab  (2hrs)

Steps 5-7 completed.  Countersunk 2 holes that will be under center hinge brackets.  Used microstop with #30 CS bit.   Being cautious to not go too deep, I proceeded in small steps until just right depth.

Final Drill #12 holes in brackets.   Then deburred all holes and scuffed parts to be primed....tomorrow.

Horizontal Stab (3hrs)

Sec.  8 -02   Start of Horizontal Stab build.    Steps 1-4 done for Rear Spar with doubler and  hinge brackets (4 pairs).  I did the doubler for front spar while I was at it, too.    Lots of deburring edges (along 9ft + spar !) including all the lightening holes.   Small diameter 3M Cut and Polish wheel (1") in air drill made quick work of the holes.  A groove worn into wheel aids in slightly rounding the edges, too.

Final Drilled holes (reaming) in for doubler to spar rivets, and spar to brackets.
