1933 Napier-Railton Chassis

Like the engine, the chassis frame, drivetrain, wheels and suspension will be scratch built. CAD drawings provide for 3D printed parts and also ensure that all the components fit together. Those drawings are now complete. 

To support the weight of the model, the chassis frame and suspension parts are largely made out of brass.

Below are photos of the unpainted assembly.

The core of the steering box is from a 1:8 scale Rolls-Royce Phantom II.
