SCP-914 is a large clockwork device weighing several tons and covering an area of eighteen square meters, consisting of screw drives, belts, pulleys, gears, springs and other clockwork. It is incredibly complex, consisting of over eight million moving parts comprised mostly of tin and copper, with some wooden and cloth items observed. Observation and probing have showed no electronic assemblies or any form of power other than the Mainspring under the Selection Panel. Two large booths (10x7x7) are connected via copper tubes to the main body of SCP-914, labeled Intake and Output. Between them is a copper panel with a large knob with a small arrow attached. The words Rough, Coarse, 1:1, Fine, Very Fine are positioned at points around the knob. Below the knob is a large Key that winds the Mainspring.
When an object is placed in the Intake Booth, a door slides shut, and a small bell sounds. If the knob is turned to any position and the key wound up, SCP-914 will Refine the object in the booth. No energy is lost in the process, and the object appears to be in status until the Output Booth door is opened. Intense observation and testing have not shown how SCP-914 accomplishes this, and no test object has ever been observed inside SCP-914 during the refining process. The process takes between five and ten minutes, depending on the size of the object being refined.
