Brief Description:    Fuselage - Prepare for final assembly, part 1
X-mas eve 2016....Preparing fuselage part for sub assembly started ! From now on, I will follow the instruction as much as possible to speed up the process. Today, I did:

- Countersinks dia #30 in the F-843 longerons
- Countersinks dia #30 in the F-844 aux longerons
- Countersinks dia #40 in the F-844 aux longerons
- Relocated the F802D L/G box plate in place, and made countersinks #30 for dimples in skins F820
- Countersinks on inboard side of F817 Seat Back support plates
- Relocated the F-804H Center Section Side Plate on the Center Section, and made Countersink dia #40 for dimples in skins F823 LH & RH.

In the mean time, André decided to provide some help. He started deburring holes in skin F820. RH first, then did half of LH.

I need to investigate if skins F820 are still useable or not. Some of the holes at the bottom have been largely ovalized during the process of drilling the longeron.
