@RequiemSoup The axis of the escapewheel carries a small drum with a thread wound around it. The thread is guided over a pulley on the left and carries a weight (you can see part of the thread). The weight is prevented from running down by the escapement locking lever. The lever is lifted by a pin on the pendulum when it requires impuls, and lowered immediately. This keeps the pendulum going in spite of frictional losses. (see W10b for the complete setup, with an other escapement).
Thanks Ben; Just what I was looking for. I cut my gears today. 1/8 th plate steel 7 inches in diameter, 8 teeth per gear and two gears. I want to power my pendulum in both directions. It weighs over 140 pounds and swings at 6 & 1/2 feet.
i discovered that wheel a couple of years ago. i considered taking a stab at designing with it, but realised that i wouldn't be able to design a gear train, and the subsequent hand movement, that would resolve a 14 tooth gear. at first, the pin hole seemed problematic, but i figured i'd use two of the 3-axles with stud (peeron part #6587), inserting the stud end into the wheel.
Ben, this is awesome! I appreciate all the effort you put foward in these escapements. I"ve recently found myself looking at Lego sets in an attempt to find pieces for building a clock. My wife has been less than thrilled about supporting such an endeavour. From your posts, I am narrowing down choices, and hopefully between existing Lego pieces and maybe future purchases I will be able to achieve my goal. Just to note: she hasn't opposed the idea, just an over-expense in pursuit.
graig, are you familiar with bricklink? you can buy new and used parts, reasonably priced and in just the quantities you need. you'll also find many of the discontinued parts which many horolegoists use for their hand movements, particulary the old typ-I half-bushes with teeth (peeron #4265a) and technic 1 x 4 plates (peeron #4263) critical in designing concentric hour and minute hands.
Me at all your lego escapements:
:O w00t
thx for the inspiration. Now I'm gonna build a machine that pushes F5 every 3 seconds to get more views to my videos, haha.

De slinger is niet gecalibreerd. Maar dat kan vrij eenvoudig door een klein gewichtje op en neer te schuiven langs de slinger.

The y bar locks the scapewheel. Unlocking results when the pendulum lifts it. Calibration is effectuated by changing the length of the pendulum.

Is the yellow bar used for calibration?

Thank you so much for making these! I've been trying to figure out how one might make escapement, and you hit it right on the head!

does it goes for ever?

@pivotman43 It stops when the weight reaches the ground. Then it has to be rewound, like any mechanical clock.

@pivotman43 There is absolutely no possibility that something goes on forever, because then it would be a perpetuum mobile.

Does this use any batteries??

@RequiemSoup
to the beat of my knowledge, all of ben's escapements are driven by weight, although any of them can be modified for a motor drive.

@RequiemSoup No, only a weight.

@BenVanDeWaal ingenious..... Care to explain?

@KEvronius Thank you. Part 6587 is really the best solution.

d'oh! i overlooked your mention of that part in your description. i've got to learn to read the fine print.
