Tailcone Attachment

*Pre-COVID-19:

After getting one of my buddies over, I was able to do the initial attach of the tail to the fuselage. Initially we attempted to install the tail with the F-1074 Tail top skin and the F-1006 (A and C) ribs installed. This honestly just made things more difficult. Once we removed those pieces, and used my HF hydraulic table, things went much better!

With everything clecoed together, I then began to match drill the longerons, followed by match drilling the remaining holes in the skins to the underlying structure (I’m oversimplifying what is in the drawings). Don’t forget to fabricate the shims, then countersink everything called out in the plans.

Once everything was drilled, pull it apart, debur, dimple (as necessary), and re-assemble. Again, I found I could re-install the tailcone on the fuse by myself with some critically placed saw horses, my hydraulic table and the F-1006A/C rib removed. Once the tail was attached with a few clecos and bolts, I could insert the F-1006 rib without too much trouble. This did require an offset rivet set to allow me to get the F-1006B rib riveted in.

With the tail attached (and mostly riveted together – need to get a helper so I can get the bottom skins riveted), I decided to build an updated fuselage stand so I could access the bottom of the airplane. This is necessary for me to begin the Air Conditioner scoop install. Basically some 4×6 lumber, some longer bolts and some casters. This setup does still require a sawhorse under the tail for now.
