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.
