Fuselage - AFT Section
I drilled the J-Channels, and match drilled all of the bulkheads. I still have to drill all of the holes on the bottom.
After installing all of those clecos on the aft fuselage the other day, my hand ached like crazy the next few days. I think the main problem was with all of the clecos in the bottom of the bulkheads. I had a hard time with every single hole, and bent quite a few clecos. So, today I used my cleco gun for most of the clecos, and my hands felt fine the next day.
