Four Bar Chain Mechanism

The mechanism is assembled in an anodized aluminium structure, with painted steel panel.
The bars, made of anodized aluminum, can be connected at different lengths using easy to fit knurled bolts.
The discs include a scale to measure the input and output angles accurately with the aid of a methacrylate indicator. The rotary motion of one of the discs is transferred through the bars and generates the rotary motion of the other disc. It is made of anodized aluminum and consists of two rotary elements (graduated discs) mounted on ball bearings.
