Working K'nex Clock





Introduction: Working K'nex Clock

About: I make instructables. I also have a YouTube channel at!

This design keeps accurate time using a geared-down K'nex electric motor. Numerous closely-meshed gears provide smooth movement for the hands of the clock.

Don't relax yet, the hard bit is still to come!

Step 5: The Fiddly Stuff

THIS is the hard bit. These are all the axles used.

Not essential, but I advise you to add them as they make the clock more sturdy and make it look nicer.

    wow, this is truly amazing!!!!!

    nice clock but if you don't have that motor can you use a different one or no?????

    Well it's not the sturdiest thing in the world at this point; it should be wobbly but not to the point where if you let go it would collapse.

    Thanks, I'm not the original creator of this, I simply brought it to instructables to give it the views it deserves :)
    Also, I would greatly appreciate it if you check out my latest forum topic :D

    You buzzkill.
    I've wanted to make a k'nex clock for ages and now i finally find one, and it uses too many pieces and some pieces I've not even heard of.

    Apparently the motor used in this ible has an rpm of 30. A battery powered one (red battery pack, clear engine) has an rpm of 32 rpm, so there isn't too much in it.
