The rest of the tailcone (before the turtle deck) is just straightforward clamping and drilling.
- Installed all 4 lower cross ties between the buldheads and against the lower skin (fuselage is on it's side in these photos). Clamped, pilot drilled and cleco'd them to the bottom skin, then pilot drilled all the holes joining the lower cross ties to the bulkheads (photo #3).
- Went back and updrilled EVERYTHING that is called to be updrilled at this time, which is nearly everything.
Next: time to deburr!
Bottom skin updrilled
Tailcone on its side. It was very easy to install the lower cross ties & bottom skin this way.
