How do I wind a mechanical clock?

Use the matching key on the winding arbor and turn it gently until you feel resistance. Do not overwind, as this can snap the mainspring. Keep track of whether the movement is an eight-day or fourteen-day train so you know how often maintenance is required.

Why does a fusee clock keep better time?

The conical fusee pulley compensates for the declining power of the uncoiling spring. This delivers equal force to the escapement throughout the run. Simple spring-driven clocks lack this device and tend to lose accuracy as they wind down.

Where should I place a skeleton clock?

Keep it on a stable surface away from direct sunlight, drafts and damp air. The glass dome must remain in place to keep dust away from the exposed brass wheels. Level the surface carefully so the pendulum or balance wheel swings true.

How do mechanical singing birds work?

A spring-driven motor rotates a small brass cylinder with pins that lift levers connected to bellows and whistles. This creates the varied notes and throat movements of the bird. Feathers cover a papier-mâché or metal body housed inside a brass cage or box.
