This tutorial in a slightly
different form originally appeared on the 2OO1: A Space Odyssey
been a big fan of the film 2OO1: A Space Odyssey since I
first saw it in 1969 at the age of 13. I was a little too young at the
time to appreciate the gist of the film but it kept me coming back to see
it again and again over the years.
2OO1 also changed forever
the way we view sci-fi "hardware" which until then, still seemed influenced
by the Buck Rogers serials of the 1930s and the German V-2
rockets of the '40s.
| I was thrilled
when Aurora and Airfix both released kits of the Orion space plane
and the Moon Bus but was disappointed that no other kits from
the film were produced, especially my favorite spacecraft,
It took about twenty years for
Discovery to be produced by "garage
kit" manufacturers, home hobbyists who make their own molds and cast
kit parts by hand. Of the kits that I knew that were available in the early
1990s, the best and most readily available was made by Lunar Models.
| The kit came in a
heavy corrugated cardboard box with a label and photograph of a finished,
painted kit. Larger parts were in their own separate bags, smaller parts
separated into two smaller bags and one bag contained the fuel pods which
would be lined up along the ship's spine. The 3 long spine parts were wedged
into the box diagonally, un-bagged.
The kit is patterned
after the Discovery as it appeared in the 1984 movie 2O1O:
The Year We Make Contact and is slightly different from the Discovery
in 2OO1. Some modifications to the kit will be needed to
make this model look more like the Discvovery from the 1968 film.
not easy to come by in the early 1990s. There was no Internet like we have
today. The best resource I had was a VHS print of the film which I could
view with a 19-inch TV set. Even with freeze-frame, TV image quality of
the day was just not up to the task of providing an image sharp enough
for close-up detail.

an intimidating kit. It includes 84 polyurethane resin parts, many of which
are cast poorly. Most of the parts would need some work and a few would
be replaced with scratch-built parts. This was the early days of hand-cast
garage kits when casting quality could range from the good to the bad and
in some cases, the ugly. This kit would include samples of all three.
"Command Section" had its problems. The middle of the three pod-bay doors
showed signs of some serious mold deterioration. There were some resin
lumps and berries that were so bad that it became necessary to grind out
the entire door with a Dremel rotary tool.
the kit came with an extra bay door to build the kit with the pod-bay open.
I used it to replace the removed door. A hold-down jig was made for the
sphere to make it easier to mill a flat seat for the new door. The 3/8
inch thick resin of the part was milled to just under 1/8 inch and the
new door was glued into place.
looked klunky and a little exaggerated with many air bubbles in the resin.
Some panel lines were at slight angles and others almost looked as if they
were scribed freehand. Most of the detail was filled with putty and sanded
smooth until the part was nearly featureless. Instead of scratch-building
the lost detail back onto the sphere, I decided it would be added back
to the model as painted-on features.
| The hollow
pressure sphere was sanded on the inside until Discovery's sealed
front window was open. The Command Room was scratch-built with sheet styrene
and model railroad bulbs. A video tape of 2OO1 was used as
a reference as was Shane Johnson's "Discovery Blueprints" which have excellent
diagrams of the spaceship's interior. Assorted decals of instrumentation
from other kits covered the back wall. The Command Room would be visible
through the narrow slot of the front window so details were kept to a minimum.
Three 3-volt model railroad lamps light the interior space - two in the
lower corners, one above the center corridor. The photo on the right shows
the finished Command Room with a nickel for scale.
| As cast,
the Command Section has eight evenly-spaced depressions which are labeled
in the blueprints as "reaction control thrusters." The Discovery
in the film had only one of these depressions on the forward right side,
just below the pod-pay door. I filled in the other seven with Squadron
brand filler putty. The air-lock door on the left side of the pressure
sphere was way too deep and looked more like a trench than a door. It was
also filled with putty. When the putty was cured it was wet sanded until
flush with the curve of the sphere. Cured Squadron putty expands when it
gets wet and shrinks when it dries. The putty on the air-lock door shrunk
just enough to give it a better, more subtle recess.
the most obvious problem with the Command Section was that the part was
short by 1/8 inch which caused a mismatch between the sphere and the flange
behind it. A spacer made from 1/8 inch thick sheet styrene was glued to
the back of the sphere which corrected this problem.
| The conical
section behind the Command Section was replaced with a section of a styrene
Estes Rocket nose cone detailed with a one-half ounce half-and-half container
like the kind served in restaurants. This improved on the accuracy of the
part. The part was then drilled out and a piece of 1/8-inch K&S brass
tubing was glued inside to reinforce the joint between the flange and the

section, 20-inch long spine is made of resin cleverly cast over brass for
strength. The two ends are cast over brass rod and the center section over
brass tube, making for a secure fit as well as providing locator pins for
the Command Section in the front and "Reactor Section" in the rear. The
spine of my kit was fairly straight and cast pretty well but I have heard
that owners of later kits weren't so lucky.
| The spine
was nicely molded with lots of fine detail. One of these details, the spine
"Segment Clamps" (arrow, right), run along the spine in 36 places. Many
were broken and were replaced with pieces scratch-built from sheet styrene.
to view the instructions that came with the kit. (Adobe
Acrobat Reader required.)
| Lunar's instruction
sheet has a diagram showing the locations of the 62 fuel pods which come
in three sizes and are positioned along the spine. Though confusing
at first glance, the instructions were helpful in arranging the fuel pods
in their accurate configuration. In order to ensure that all the pods wouldn't
look uneven when glued to the spine, a jig was made to hold each one down
on a milling table and they were all milled to the same thickness. When
glued to the spine, the pods lined up fairly straight.
communication antenna and mounting were unusable. The base was inaccurate,
being modeled after the Discovery in 2O1O and the
antenna mast was not only warped but short cast. The three dishes were
anything but dish-shaped and the main antenna's probe was so covered with
flash and resin lumps that it took me a while to figure out what it was.
| New dishes
were made from sections of spherical fuel tanks from another kit and a
new swiveling mast and base were scratch-built from sheet styrene and acrylic
rod. A new probe for the main dish was made by chucking a piece of 1/16
inch acrylic rod in a hand drill and shaping it lathe-style with a needle
file. Dish cross members were made from strips of .020 inch sheet styrene.
| The Reactor
Section was detailed using a combination of K&S brass wire with spare
parts from other kits. This hollow cast part was almost problem free with
an easily cleaned up mold parting line. 1/8-inch diameter holes were
drilled in the front and back ends of the part and a length of brass tube
was glued inside the piece flush with the front and extending 3/8 inch
from the back (indicated by the gray stripe in the photo at left). This
would help to secure the joint between the reactor and the back end of
the spine and would also provide a locator pin for the center engine.
| One of the three
engines looked as if it were cast during another run of the kit. While
two of them were cast in light tan resin with very sharp detailing, the
third was a darker (maybe older?) resin with very soft details and flaws
in the resin such as air bubbles and "mold berries." It was cleaned up
with a Dremel grinding tool and the addition of sheet styrene.
| The EVA pod
is beautifully detailed for its size, about 5/8 inch high. Though not entirely
accurate, I thought it looked good enough to leave alone. It comes with
a pair of very delicate 5/16-inch long resin arms which, after flash removal
show a lot of detail and really look good for the scale. The "WARNING:
EXPLOSIVE BOLTS" marking on the door (which may or may not actually say
that - it's too tiny to read) is from a 1/72 aircraft kit.
| The model
was painted with Tamiya acrylics. Using my trusty Badger 150 airbrush and
of masking material, I painted a complex series of panels in various shades
of light grey on the Command Section. in an attempt to make up for all
of the detail sanded off in the process of cleaning up a less than perfect
casting job, small detail was painted on.
The spine and reactor/engine
sections were spray painted with medium gray automotive primer. Details
were then colored with a black Sharpie marker. The parts were then airbrushed
with a coat of light grey acrylic paint. The black Sharpie is just barely
visible under the gray coat.
long Discovery was mounted on a scratch-built display stand. The
stand's forward support post is topped by a 1/8 inch phone plug which connects
to a phone jack below and behind the Command Section and provides the 9
volts necessary to light the Command room. The EVA pod is mounted on a
1/8 inch piece of acrylic rod.
I didn't keep a record of my work on this model, I'm sure that with all
the part cleanup and additional scratch-building the Discovery took
at least 40 hours to complete. Though this kit presented many challenges,
it was a lot of fun to build.
In 2002, the
model was filmed for a television program on the Discovery Science Channel
The Great Books - 2OO1: A Space Odyssey which
examines the writing of the novel and 1969 film by Arthur C. Clarke and
Stanley Kubrick. In a few scenes, actors portray Clarke and Kubrick working
at a table covered with typewritten ideas and models from the movie. Discovery
is visible stretched across the middle of the table. The show is available
on YouTube and can be seen by clicking on the image below. The model is
shown at about 18 minutes into the show.
