BASIC FUSELAGE ASSEMBLY
INTRODUCTION
.....
Jigging the fuselage is your first major assembly task on the Q2.
Because the Q2 fuselage shells are provided you in a prefabricated form,
jigging is simplified, and there is no messy carving of urethane foam, as
is the case with other homebuilts. Perhaps more important, the average
builder will find that with the prefabricated fuselage shells, a
smoother, aesthetically more pleasing shape will result (carving foam
puts the final shape and beauty in the eyes of the carver) and that the
final weight will be as much as 30 lbs lighter since all excess material
is removed through the prefabrication process and the vast majority of
finishing weight is eliminated. But most important probably, is that you
can be sitting in the cockpit making airplane noises in a very short time
a most definite incentive to finish the rest of the aircraft!
PRELIMINARY TRIMMING AND JIGGING OF THE SHELLS
.....
The fuselage shells are shipped to you in four sections - upper and
lower forward fuselage and upper and lower rear fuselage. The upper/lower
longitudinal cut line is arbitrary; the cut line that separates the
forward fuselage from the rear fuselage coincides with the fuselage cut
line used for making your Q2 trailerable.
.....
The shells are long, and must first be trimmed back to the proper
length using the trim lines on the parts. If a particular trim line is
difficult to read, trimming the part during jigging will yield the best
fit. The parts should be inspected by the builder for quality control
using the Composite Materials Education chapter as a guide. In addition,
if you measured carefully, you would find that although the shells will
look symmetrical left to right, that there is some asymmetry from left to
right. This is nothing to worry about, just note for future reference.
.....
Locate the 5 fuselage female jigging templates and the bulkheads
that you made previously. Study the sketches to obtain a feel for where
jigging templates were setup to jig the fuselage approximately level with
WL15 when the jigging table is level; note that the longitudinal fuselage
spit line does not coincide with a WL. Establishing a WL is important so
that the main wing and canard can be mounted later at the proper angle of
incidence.
.....
First, you should setup the fuselage female jigging templates at
the FS locations called out on the templates. Use some triangular corner
blocks made from scrap lumber to hold them vertically temporarily. Next,
set the lower fuselage shells into the fuselage female jigging templates.
Do not be concerned if you find it necessary to move the fuselage female
jigging templates fore and aft to achieve a good fit; remember that you
are not looking for a perfect fit, just a resting place for the shells
while you assemble the fuselage. Once the locations of the fuselage
female jigging templates have been established, Bondo them in place so
that they will not shift position and rest the two lower shells into
them.
.....
Trail fit the upper fuselage shells onto the bottom ones and make any
trim line corrections at this time. It looks like an aircraft doesn't it?
