  • I learned something today!

  • nice documentary thanks

  • Excellent work! I learned a lot about gears and clocks. Good job! Thank you.

  • Thank you for all these videos. I think, if you would get enough advertising, you would have like a million viewers.

  • great video mate. If you ever get to NZ check out the clock museum in Whangarei.

  • what happens when the weight touches the ground? wouldnt the clock stop? how do they fix this problem

  • @blueshift314 Clocks are wound regularly to ensure the weights never reach the ground. Most clocks run for a week with a reserve of one day. (so-called 8 day clock) The clock weights can then be wound up again on a specific day of the week. Some clocks only run for 30 hours. Requiring daily rewinding with a few hours reserve. It is amazing to think that some clocks have been wound laboriously for centuries without a break. (except for occasional repairs) 

  • Great Video. We also restore and work on clock towers and bell towers. Smith's Bell and Clock Service, Inc.

  • the clock is powered by the weights like usual, but on a clock tower, what is it that resets the large, lowwering weights?

    its not like how on a grand father you just wind it back up once a week...

    where does the force come from? and what administers it?.....

  • how often do you have to rewind a normal house clock?

  • great post. thanks.

  • I want that clock kit

  • i love this video!

  • Grüße aus der Oberlausirtz!

  • great video thanks a lot

  • wow, can everyone see the cubes in the center of the clock?6:02

  • where did you get this set?

  • Nice video. Even better to see one of our strike clocks working in Canada. The John Smith comany is still going and still in the Smith family.

  • what happens when the weight falls all the way down? only got to see 5min of the video, is it explained after?

  • rewind the cord

  • you wind it back up.

  • how are the pendulum oscillations sustained?

    i meant that the oscillations may die out because of friction, how is this prevented?

  • Good question - the escapement mechanism is designed to "kick" the pendulum on each stroke. The force to do this comes from the suspended weight.

  • IF there was no friction on the pendulum, the weight would be useless. but since there is, the kinetic energy by the weight falling replaces the EXACT amount of force that was lost to friction. get it now?

  • wow i need to buy myself a kit like that great video dude

  • We should have a clock like this at Morrisons. Instead of our 2 face silent electric clocks these are huge clock tower face style dials I would prefer the 4 face clock on this video!

  • AWESOME

  • thanks

  • could you post a video on galileo's pendulum clock

  • gears rocks!!!!!!!!!!

    - jojo

  • Good work!

    Jordan, at the Canadian Clock Museum

  • Amazing how people have created technology such as these clocks over the years.

    Still, I find this video quite interesting how a clock works. You should make a video about how digital clocks work...

    You don't 'ave to, just suggesting...

    Keep up the good work!

  • It's amazing how we take something like this for granted. Such intricate details all to measure one second of our lives.

  • Great video like always. Thanks!

  • great video, thanks.

  • very well put together examples of how gears are used in clocks. I will definitely be passing along this video to my homeschool friends and family. Keep up the excellent videos!

  • neat stuff.  hooray for science!
