Introduction
One of the most interesting
merchandising items in the Britten catalogue is the
hand-built scale model of the V1000. The story of the
construction of this 1:12th size "baby Britten" is a
tale of resourcefulness that rivals the building of
the real thing.

Small, perfectly
formed, perfection in miniature, the "baby
Britten" is a labour of love representing 3000
hours of development for New Zealand model
enthusiast Jim Wylie. Like the real Britten
V1000, the prototype of the 1:12 model was
designed and constructed after-hours using good
old-fashioned Kiwi ingenuity. Says Jim Wylie,
an avid Britten supporter and lifetime
motorcycle enthusiast "I knew that such a
project would be enormously time consuming and
many difficult problems would have to be solved
but, having often dreamed of creating a model
motorcycle from scratch, I couldn't pass up the
opportunity".

Genesis
The idea was first suggested to
Jim by John Britten in 1992. The pair were taking a
breather during the annual BEARS speed trials for
British, European and American motorcycles. Held on a
long stretch of closed public road outside
Christchurch, the event had become a showcase of the
Britten V1000's world-beating performance
capabilities with speeds reached of over
180mph.
Builder-designer John Britten
wanted the fans to have a more tangible involvement
in his futuristic dream machine, and saw the model as
an affordable way for diehard Britten enthusiasts to
own a piece of the legend.Jim Wylie, a former
professional architectural model maker, had built up
many kitset motorcycle models so he knew the problems
that lay ahead.
"Even before the work could
begin important decisions had to be made," he
remembers, "what form would the model take ? Should
it be a kitset, a made-up model ? What scale should
it be ? How would the pieces be manufactured
?"
"At length we decided it would
have to be a kitset and that 1:12 was the ideal
scale."

The Hard
Yards
Large-volume model
manufacturers make parts in injection-moulded plastic
but the enormous cost of the dies meant that Jim
turned to a more traditional method."The only option
seemed to be to spincast them in pewter, a process
used by makers of small-scale model car and railway
kitsets," he says."Having no experience of this
technique I tracked down a local spincaster for
advice".
Armed with an assurance that
his proposals were feasible, Jim set to work,
painstakingly photographing every part of a real
Britten V1000. These were translated into scale
drawings from which brass masters for the mould would
be made.The operation soon involved the Britten
workshop with some major parts, such as engine,
wheels and bodywork, roughed out on the lathe by
Britten toolmaker Rob Selby and Christchurch
model-maker Roy Parkinson.
All other parts were carved out
by hand from solid brass using basic model-making
hand tools such as miniature metal saws, needle and
riffler files, rotary burrs, and chisels and scrapers
ground from old hacksaw blades. "I tried to
incorporate as much detail as I could to ensure the
model resembled the real machine as closely as
possible," says Jim. A steady hand, a good eye and
artistic flair were the main skills Jim
employed.

To make just one
tiny part, he would cut out a suitable sized
block of brass so that plan and elevation
drawings could be glued to the top and sides.
The outlines were scribed through to the metal,
the shapes carefully cut out then hand carved
with files and scrapers before a final polish
with sandpaper.
|
|
|
The V1000's distinctive
bodywork was cleverly made by soldering two blocks of
brass together and carving out the fairing, tank and
seat as a unit.
"The soldered join was on the
centreline so that once the sculpting and finishing
had been done the piece could be heated and the two
halves separated vertically," says Jim. "All excess
metal was then removed from inside the separated
halves."
Smaller parts, such as the
handlebars, were built-up by soldering together
combinations of hand carved pieces and lengths of
brass rod.

Some parts were almost as
difficult to build as the real parts on the Britten
racer. For example, it took the factory 80 hours to
bend and weld the V1000's curvaceous exhaust system.
Jim's model version was scarcely less tortuous. "The
complex bends were made by carefully heating and
bending copper wire of the correct gauge until the
right compound bends were achieved and then carefully
silver soldering each pipe to the collector", Jim
says.
The smallest parts threw up
some of the biggest challenges. The embossed Britten
script on the engine's cylinders was engraved onto
thin strips of brass which were then soldered onto
the engine master, while the underseat radiator was
given a realistic look by soldering fine mesh to the
underside of the rear sub-frame section.
"In total the work on the model
masters took around 2000 hours, " says Jim.
Which Bike to Model ?
The real Britten was rapidly
evolving as a racer during this time. "Like all
racing motorcycles the Britten V1000 has undergone
constant design changes", says Jim. "As I was
building the model the real machine changed so much
that we realised the model would have to be of a
particular machine and preferably a race
winner."
"When Andrew Stroud realised
John's goal by riding a Britten to it's first Daytona
Battle of the Twins victory in 1994, we decided the
model should be a replica of that machine."
Prototyping the
Model
Test castings proved the
complete set of parts would cast cleanly from the
masters and fit together as planned but, there was
still a heartbreaking amount of work to be done
before the model could be called finished.
Says Jim " Moulds had to be
machined for the rubber tyres, formers had to be made
for the vacuum formed windscreen and muffler heat
shields, tiny machine screws had to be sourced,
springs for the shock absorbers made, artwork for
transfers drawn and jigs made so parts could be
drilled for axle fitting, and so on."
Undaunted by a mountain of tiny
tasks, Jim also embraced the demanding job of
designing the instruction booklet and packaging for
the model kitset. "To draw the exploded diagrams that
show how the parts fit together I had to set the
parts up as they appear in the drawings and then
photograph them," he says. "Then I made enlarged
photocopies of these photographs and traced the
outlines of the parts over a light box".

Packaging the Finished Product
|
Jim wanted the
packaging to reflect the quality of the model
he had so painstakingly designed and built and
was determined to sell it in an attractively
presented box with full-colour lid.
"Because costs had to
be kept to a minimum I also designed the
packaging myself and when no suitable action
shots of the Daytona-winning V1000 could be
found, I ended up doing the painting for the
box lid as well," he says.

|
|
To protect the parts from
damage in transit, Jim designed a special polystyrene
tray made in parts on a computerised hot-wire cutting
machine and then hand assembled. The trays were sprayed
with green flocking for a classy finishing
touch.
|
|
After more than
3000 hours the model was finally ready to go on
sale, and no-one was more enthusiastic than the
man whose bike had been copied. John Britten
quickly added it to the growing list of company
merchandise that is sold around the world and
where ever the factory team is racing.
Says Jim: "We really
didn't know how popular the kits would be but
after almost two years of steady sales the
gamble has paid off and proceeds from the
model sales are still helping the Britten
Team's racing endeavours.
|
|
|
"That's the main reason we
created the model in the first place so after all the
effort I put into it that's really gratifying. "It's
also been great to hear back from so many enthusiastic
model owners, I'm really glad that so many people have
gotten so much enjoyment from it".
