I think I know how to make this but it won't work. When I put 1 flat lego piece under the lego where the big gears are, it is to low, and when I put 2 flat pieces under it, it is to high!
I had a "crazy" idea to make an escapement but I couldn't get anything working. You have more legos than me, or are crazier, or both. In any case your ideas are awesome!
I was attempting to drive mine with a little assembly included with a "pull-back" car lego set. I don't know what that mechanism is called but it's rather like winding a clock spring I thought.
I must discourage you to use a "pull-back" thing to drive your clock. I do not know exactly what it is but it may contain a rubber band that is stretched or wound in order to store energy that can be released to the clock (the same with a spiral spring). Because the released energy per unit of time diminishes as the process proceeds your clock will be unreliable. Use a falling weight to avoid these problems; this gives a constant torque on the escape wheel or the first gear in the train.
How is the Mechanical Advantage set up in your pully? Is it same as a standard pulley with strings and gears? I was wondering if you could show me a picture of the pulley system and possibly a back view of the machine as I am trying to build soemthing similar.
It is very simple, with no (other than the visible) gears at all.
On the axis of the left hand wheel is a pulley with a thread wound around it that is guided over a second pulley on the far left (not visible, but you can see the thread). The end of the thread carries the weight.
a thread is wound on a pulley on the left wheel axis (you can see it at the far left). It is guided over a second pulley and carries a weight. The gradual dropping of the weight keeps the wheels turning.
I can not remember exactly. Somewhere between 100 and 200 g. But it depends on the diameter of the pulley you use for the wire; mine was 5 mm. The weight should be at least be able to compensate for the losses, but not much more to prevent hard collisions. This is a matter of trial and error.
Hello Ben, can you send me some pictures of the mechanism, my email addres is: hobbyt@live.com

Wow, thx for this mechanism

I successfully re-created this. Now I understand how a GE basically works. Thanks for the inspiration! :-)

mainspring - ratchet - escapement = pendulumn clock ! i can see why Doc ( back to the future) have so many clocks in his lab

escapement . i wonder is the universe is such ?
dan020350 2 years ago
lol before seeing your videos I always thought it was the pendulum driving the clock... XD

i made this clock today it took 6 gears for each hand 8,24 8,40 16,8

I think I reverse engineer it if i could see the back. It's so simple. I love it!

Try with a shorter pendulum to do ita right 1 second ;)

@BenVanDeWaal
you know, a pull-back motor could make for a nifty spring remontoire.

I was wondering how the second pulley is structured.

amazing piece of work 0.o
how does the pendulum keep its momentum?

well done, i want to make one now! lol, and swiftscripts is right, very hypnotic to watch... =)

can we get some construction details on this please?

That's not only a great idea for an escapement, but it's very hypnotic to watch.
swiftscripts 3 years ago
very nice, one question.. how much weight do you have pulling on that?
