The Lister racing car originates from a small racing car manufacturer in England. Founded in 1954 by the British racing driver Brian Lister, the company first produced vehicles for racing between 1954 and 1959. The vehicle was modified several times over the years. In order to restore the bodywork to its original condition (see Fig. 1), the vehicle came to our workshops for a complete rebuild of the outer skin.
Construction
Due to the rarity and age of the vehicle, there were no drawings from which the original shape of the body could be derived. We therefore relied on modern technology and scanned the vehicle. From the scan, we were able to create a 3D file of the outer skin, which included key dimensions such as wheelbase, track width and much more. Historical images were also used to recreate the original body shape. Using these, the shape of the vehicle could be modeled true to the original.
Production with the aid of tapping models
With the help of this CAD data, the knock models for production could be produced. The front of the knocked-on model was made from solid model plastic, while the rear was made from MDF panels using a frame construction method. The aluminum body panels were then produced using the knocking model. The individual parts could then be welded together.
Assembly on the measuring machine
Once the individual body parts had been produced, they could be mounted on the vehicle. The body parts were precisely aligned with the frame using a 3D measuring machine and installed.
