| Yes,
my very good friend Lars Ole, or "Ollie" as we call him,
has built a fairly large model of the A-wing fighter from Return
of the Jedi. This was an ambitious project for him since it
involved large-scale vacuum-forming and prototyping.
He
based his construction plans on a few pictures showing the craft
from the side, aft, top and bottom. Like me, he spent as little
time working on the plans as possible. If I recall correctly, I
believe he spent about a week at the drawing board before grabbing
for the knife.
The
good thing about this ship is that you can use the same vacuum-plug
for both the upper and lower half of the hull. With that in mind
he started constructing the vacuum-plugs. He basically just glued
a lot of styrene ribs to a sheet o styrene cut to the shape resembling
the horizontal outline of the ship. The space between the ribs was
then filled with blocks of urethane foam and about a kilo of two-component
polyester putty. This raw form was then sanded, filled and sanded
again to a smooth finish.
The
vacuum-plug was so large that we had to build a new vacuum-former
to accept it. Since the sheet of styrene required was too large
to be heated in the kitchen oven (as described in the vacuum-forming
article), we used two propane burners and a heat gun to soften
the plastic. It took the two of us to pull this off. One rotated
the frame with the styrene over the burners while the other used
the heat gun on the topside of the plastic. We actually had to make
quite a few attempts before we had the two successfully formed halves
for the primary hull, and there were a few burned fingertips along
the way.
The
vacuum-formed parts were then cut to shape and assembled. There
was a lot of waste material involved in this phase of construction.
The hull in front of and under the cockpit was cut away and replaced
with a lower, straight sheet of styrene. All the material had to
be cut away where the engines would be, and the cockpit opening
had to be cut out. All in all, Ollie did a great job in aligning
and assembling the different parts.
With
the primary hull now assembled, he could start scribing the panel
lines into the plastic. The first thing he had to do was to draw
all the lines on the hull with a pencil. He then made a few styrene
templates to follow the curves in the hull. On the back of the templates
he used double sided tape to hold them in position while scribing.
He used a small, custom sharpened screwdriver for this task. After
scribing he had to sand the hull to remove all the excess plastic
along the lines. He then had to clean the lines by rubbing the sharp
end of a styrene sheet in the cut. This was very effective and left
the panel lines with a smooth finish.
Most
of the parts for the cockpit interior were kitbashed in the ways
of the grand tradition.
The
pilot was sculpted in Super Sculpey and cured at 175 degrees Fahrenheit.
Ollie
vacuum-formed the engines and the rear end of the ship with a skill
that impressed me. The engines tubes are slightly bent and conical.
He made a plug for the outer half of the tube and formed four parts
that he just glued together. The hull conceals the inner half of
the tube, so his approach worked out great.
After
the model was finished it was time to paint - a job Ollie sometimes
finds frustrating, but with this model it went very well. First,
he applied a base coat of white, then red, then he mixed different
tones of white and red to apply on various panels throughout the
ship. Some light blue panels there made as well.
When
all the paint was applied, it was time to weather it down. To get
this effect, Ollie used the air brush quite often with a very thin
black/dark grey color, lightly toning it down. He then washed it
with white spirit mixed with black, brown, etc. several times.
The
pilot was painted with humbrol via brush. Much of the detailing
was also done with a brush. It took him about two weeks to paint
the whole model.
