Rv-12 Tailcone (Part 1)

Reference: page 10-02; 4.5 hours

Because of limited room in my shop I am holding of on Steps 1 & 2, as these deal with breaking the edges of the tailcone skins. I will come back to these steps as soon as the skins are required in the building process.

Step 3: Flute the F-1210C Angle at the places called out. Each flute needes to 'hump' in the same direction as the five-hole flange. With the five-hole flange pointing up, align the holes in the four-hole flange of the angle to the full scale illustration in the plans. Increase the two flutes until the five-hole flange matches the curve shown on page 10-02.

Step 4: flute the F-1208-L & -R, F-1209L & -R, and F-1210-L & -R fuselage Frames to align the flange holes. Flute the 'hump' of any flanges toward the web of each fuselage frame.

Step 5: Rivet the F-1208A Wear Plate to the F-1208-R Fuselage Frame as shown.

Step 6: Cleco, then rivet the F-1208-L to the F-1208-R. Cleco, then rivet the F-1209-L to F-1209-R.

Hereafter, refer to the riveted F-1208-L & -R as the F-1208 Frame, and the F-1209-L & -R as the F-1209 Frame.

Step 7: Cleco the F-1210B Plate, and F1210C Angle to the F-1210A-L & -R Fuselage Frames.

Step 8: Match-Drill #30 the two holes from the F-1210A-L & -R Fuselage Frames into the 1210C Angle. Disassemble and deburr.

Step 9: Final-Drill #12 the F-1210B Plate four hole above the frame.

Step 10: Rivet the F-1210A-L to the F-1210A-R Fuselage Frame, the F-1210B Plate, and the F-1210C Angle together using rivets called out.

Builder's note: Notice the top of the frame is riveted with AN470 rivet NOT pop rivets!

This completes page 10-02 and my work for the day.
