In this video the clock is shown on a mockup sub base surround and can be seen just below the clock's brass base. This wooden surround hides a redesigned structural base located within the mockup surround. This new base allows the machine to be placed on any sturdy table top without any needed modifications to the table. The case is also a temporary piece.
