September 1, 2021 After completing the model of the Trillium I went
looking for a model engineering project. To get information on the car I went to the Mercedes
Benz archive web site and to the German November 26, 2021 After two months of machining I have the majority of the model created. To start I needed a scale drawing of the car. An
image was loaded into Turbocad and using the features
Tires have yet to be installed on these rear wheels. The wheels of models like this always cause me some
anxiety so they are the first things I make. The rims are

On the full size car, the shaft holding the forward sprockets is split inside of the two flat belt pulleys and connected by a differential between the pulleys allowing the rear wheels to revolve at different speeds when the car is turning. On the model there is not enough room for a differential so the shaft driving the forward sprockets is one piece. Benz build five cars, each with some modifications from the original design, which made building the model difficult in some cases because pictures of the different cars were not clearly defined as to which model was being shown. In order to have the model accurate to the original design it was built based on the patent Benz registered.

The front of the car is seen here.

Here we see the cam shafts along with the intake and exhaust valves. Also, the piston rod and crank shaft are seen above the fly wheel. |
