The Birth of an SMTS Model

From the production of the original patterns to the complete item, every SMTS model follows the same hand crafted procedure.

Photo 1 - After photographing and measuring the prototype, a scale drawing is made from which the pattern maker will produce the brass original. This pattern, or master, will take some 4-6 weeks to make and will be broken down into the same component form as the finished model. The pattern maker's skill is not only in reproducing the car in miniature but also doing so in a manner that can be used in production.

Photo 2 - A round vulcanised silicon rubber mould is then taken from the pattern. This mould is spun in a centrifugal casting machine and molten whitemetal, an alloy of tin and lead, is poured into the mould.

Photo 3 - After a minute or so the whitemetal solidifies, the castings are removed and passed to the fettling department, where any burrs and casting imperfections are eradicated prior to painting.

Photo 4 - The models are spray-painted with automotive paints, a great deal of research and care being taken to ensure authentic colour matching. An etching primer, which adheres to the metal, is first used, followed by base coats, top coats and lacquer. In all five coats of paint are sprayed onto each model with careful quality checking and rubbing down between coats. Decals are applied before lacquering.

Photo 5 - Then on to the assembly, where models are built in small batches. The main components are screwed together, the model fitted to a base with details such as headlight lenses and photo-etched wipers added last of all.

Photo 6 - Finally, after a quick clean and check over, the model is ready to be packed and dispatched.
