The mechanical aspects of the project were mainly focused in the areas of pulley placement, and pulley to motor attachment. The other major component in choosing a cable over chain system was the nature of the heat in the oven. Specifically the heat would cause problems with keeping the chain properly lubricated. The only notable problem with the cable system would be in the area of cable stretch, this can be resolved by simple applying more line tension when required. The operations outlined below are a complete set of all functional required steps to operate, and or reset the controls at any state or mode of operation.
