Space Shuttle Themed Pendulum Clock

The result of the last two years of my work, this escapement mechanism combines my two passions, space vehicles and clockwork mechanisms!

As I learned CAD, I felt that combining my childhood interests in space and clockwork in an escapement mechanism would leave me with a deeper understanding of mechanisms and CAD design.

I started two years ago, designing the initial files and researching the geometry. After a failed attempt due to tolerance issues, my second try had everything fit flawlessly!

I combined my 3D printed parts, 608 bearings, and gear mechanisms together to create this clock with a space shuttle pendulum. Last year, Hackaday featured my project on its website! https://hackaday.com/2018/06/21/clock-this-a-3d-printed-escapement-mechaIt was amazing to see my project featured on a site I visited daily!

  • 1 × 3D Printed Parts I have uploaded my files to Thingiverse here: https://www.thingiverse.com/thing:2917826
  • 2 × 608 Skateboard/ Fidget Spinner Bearings These bearings ensure the project ticks smoothly.

  • 1
    Axle Shaft Assembly

    Push 1 608 bearing through the axle shaft, all the way down. Adhere using hot glue or other similar method. Next, adhere the bearing in the lower hole of the bracket. On the other end, adhere the spacer, then the pendulum on the outside, making sure the entire assembly is level and aligned. 

  • 2
    Drive Gear Assembly

    Push 1 608 bearing through the shaft of the drive gear, all the way down. Adhere using hot glue or other method. Next, adhere the bearing in the upper hole of the bracket. Finally, glue or attach a piece of string approximately 30 cm long to the shaft, and attach a weight to the other end of the string.

I like it! What are the metal discs shown in the pendulum? They look like magnets but I don't see a need for magnetism in this design. Is this extra mass to help maintain momentum?

  Are you sure? yes | no

@Mike Szczys You're right! The metal discs are in fact magnets, but I'm using them mostly as decorative components.
