Empennage

Horiz Stab (3.5 hrs)

Sec 8-4, steps 2 - 7:   For Doubler on Front Spar, Final Drill all the #30 holes, then  C.S the 12 specified holes.   With top and bottom Caps cleco'd, also CS the middle 9 holes on flanges.

Disassembled all parts to deburr all the holes (lots !)  Buffed the parts with 3M Scotchbrite, then cleaned with Acetone.   I was actually able to prime outside, since temp was unusually warm  (74 degrees ) for early March in central Illinois.   Nice to not have to set up and use the spray booth.

Ready to re-assemble and rivet per Sec 8-5.
Prior disassembly to scuff and prime....
