Design Decisions, Rational & Analysis
In designing the structure we did not conduct any analysis. When designing we determined that the weight of the clock was not enough to have to use metal supports or be overly concerned about parts breaking due to weight. That being said we carefully thought about our design.

It was critical that the subsystems be supported at the required height from the ground accurately. The distance between the escapement and pallet or the winding gear and the gear train must be +- 0.01 in from the calculated distance. Using drawings we put in the known distances and calculated where supporting plates needed to be, L bracket height, and if cross supports were needed. Each subsystem sits on its own plate that is supported by the wooden sticks below it. L brackets hold the sticks and plates together. L brackets are used for increased horizontal stability and to keep the wood from splitting.

As a team we worked together to sketch out the overall design. Knowing the gear train dimensions, pendulum length, and height of the winding assembly we could determine the overall structure dimensions. We also knew to consider how much space the weights would need to drop and how we would be able to work on sub-assembly components when fully constructed. A glass plate will be placed in the front wall so that the oscillating pendulum and the dropping weights can be seen by any passing observer. The back wall will hinge open to allow for easy access to all sub assemblies. The winding shaft will be accessible through the back plate as well with the help of the winding key.
