Module 3– Unit 4
The Development and Construction of the Car
Body
Using wood and clay allows for modifications to be made easily. At
the same time, design engineering personnel construct models of
alternative interiors so that locations of instruments can be
determined.
A ¼ or ⅜ scale model is produced from the stylist’s drawings to
enable the stylist designer to evaluate the three-dimensional aspect
of the vehicle. These scale models can look convincingly real. The
clay surfaces are covered with thin coloured plastic sheet which
closely resembles genuine painted metal. Bumpers, door, handles
and trim strips are all cleverly made-up dummies, and the windows
are made of Plexiglass. The scale models are examined critically and
tested. Changes to the design can be made at this stage.
Full-size Models
Figure 12: Scale Model Maker at Work
A full-size clay model is begun when the scale model has been
satisfactorily modified. It is constructed in a similar way to the scale
model but uses a metal, wood and plastic frame called a buck. The
clay is placed on to the framework by professional model makers,
who create the final outside shape of the body to an accuracy of
0.375mm. The high standard of finish and detail results in an exact
replica of the future full-size vehicle.
