Picture of Laser cut Clock escapement and Pendulum
After several prototypes and failed attempts, I managed to create a consistent clock escapement as part of a larger kinetic sculpture. This model is based on a variation of the deadbeat escapement. Escapements in general work by limiting how fast potential energy is released. Since the escapement ensures a consistent time between swings of the pendulum (adding a small amount of energy back to the pendulum as it swings) we rely on the escapement in order to tell accurate time in mechanical clocks. These directions tell you how to create the functioning pendulum and escapement set, but it will not run without adding a spool and weights to the end of the rod connected to the escapement gear (shown on top).

I purchased the majority of my parts through McMaster Carr, but you may find alternatives elsewhere.

You will need:
10   1/4" shaft collars (single set screw)
10   1/4"-20 hex nuts
Approximately 16" of 1/4"-20 steel threaded rod, cut into two 4" pieces and one 6" piece
5" of 1/4" steel smooth rod
One roller bearing with interior diameter of a 1/4". The outdoor diameter is flexible as long as you change it in the laser cutter      
2 1/4" sleeve bearings. Flanged or regular both work (I use one of each in this instructable)
Set of Laser Cut parts which include two identical frame pieces, an escapement gear, and a pendulum with the pair of necessary      
        (if you wish to change your escapement type, I recommend Clock and Watch Escapement Mechanics by Mark V. Headrick)

     1/4" wrench
      Allen wrench (same size as your set screw)
     Gorilla glue or epoxy

Thank you for this instructable, I have been looking for an example of making an escapement, regards Doc Cox

Nice, I'm thinking I really need to get a laser cutter, they seem very versatile.
