Lego Clock Escapement W15

Lego Clock Escapement W15: 6-legged 1-arm gravity escapement. The wheel is a Technic Plate Rotor 6 Blade (Water Wheel) No.64566 (Bricklink.com). Some things have still to be adjusted more carefully; The time dt for impulstransfer Fdt is very short, because the arm is lifted again by the next leg; moreover dt, and thus the impulstransfer, may not be constant. A remedy is to attach a fan-fly or fly-wheel to the rotor-axis or to a fast rotating axis geared with this , to reduce its angular velocity (but not its impact on the arm). Another possibility is to use 3 arms, rather than 6. To make dt constant a banking pin would suffice.

I would like to request another video of this escapement, but not so close, so I can better study the impulse transfer.

These escapements always get me so excited. Would love to see more. DAH.

@mechanicsnut Thanks for your comment. Regarding your request: there is nothing more to see, except the pendulum and its bob. Actually, I think this is not a good escapement, because its frequency derives from the moment of inertia of the scapewheel and the applied torque, exactly what you want to avoid with a gravity escapement. I try to make improvements.

How does this one keep the pendulum going? I can't see it.

man that clock makes me sleepy bec. of the ticking sound and i love it im sleepy bec. the acts im waiting for someone like 3 hours....
