Setting the clock

This clock is a complicated mechanism, you have to pay attention to this tips before starting building your clock :

  • It is better to have already watch a mechanical clock to understand how it works
  • It is better if you have already build other big LEGO model with lot of gearing
  • Has a tiny but heavy bottle, in order that the bottle don’t touch the pendulum when it goes down. Of course you can use metal weight. Require weight is about 650gr with 50mm of maximum diameter
  • Building and make it works is a challenge, so don’t demotivate if it doesn’t work at first
  • Please watch the video below to set up the clock properly :

Then, note the building is composed of many moving axle and gears in the drivetrain. Please pay attention to not stress the gearing, axles and bushes, and bracing correctly each, in order to have free rotation on every axle to avoid problem of functioning. I highly recommend to use new parts, especially on the axle and liftarm and connector (or a silicone oil if you parts are too damage).
