Fuselage
(continued)
44.
When F33 is completely dry, remove the tape, and bond in place with CA.
45.
Shaping the Nose -
Use either a hobby knife or small razor plane to remove most of the
excess wood from the
top
and the
bottom
of the fuselage nose. Switch to a sanding block
loaded with 120 or 240 grit sand paper to rough in the finished shape of the nose. Next,
concentrating on the
top
of the nose, round the laminations on each side of F33, to flow
them smoothly into the contours of the formers. Sand the edges all the way
down
to the
etched line on the fuselage sides. Round the
top
and sides of the fuselage
front,
to flow it
smoothly into the sheeting and upper laminations.
46.
Turn the fuselage
upside down
, and shape the
bottom
of the nose. Use a sanding block to
sand in the angles where the
bottom
laminations meet the landing gear pocket. Ensure that
the laminations are sanded smoothly into a curved shape under the
middle
and
front
of the
nose. Sand all the way
down
to the etched lines on each side of the fuselage. Round the
bottom
to flow smoothly into the
bottom
of the nose.
47.
Sand the
rear
of the fuselage bottom stringers parts F20, to flow smoothly into the fuselage
bottom F19.
Set the completed fuselage aside until required in final assembly.
Tail Surfaces
48.
Assemble the vertical stabilizer from parts Va and Vb (sheet 06/10, 1/20 in. balsa). Bond
with CA. Assemble the rudder from parts Ra and Rb (sheet 06/10, 1/20 in. balsa). Bond
with CA.
Do not glue the rudder to the vertical stabilizer.
Lightly sand the completed
surfaces, and set the vertical stabilizer aside.
49.
Lay the rudder on the work surface with the
left
side facing
up
. Align the leading edge of
the rudder with the edge of the work surface. Use a sanding stick or sanding block to sand
a 45-degree bevel in the
left
side of the leading edge of the rudder.
50.
Locate the horizontal stabilizer part H. Lightly sand it, then set it aside. Assemble the
elevator from part E1 (sheet 10/10, 1/32 in. ply) and two E2s (sheet 06/10, 1/20 in. balsa)
and bond with CA. Lightly sand the completed elevator.
51.
Lay the elevator on the work surface with the leading edge aligned with the edge of the
work surface. Use a sanding stick or sanding block to sand a 45-degree bevel along the
entire leading edge. The bevelled side of the elevator will now be referred to as the
bottom
.
