@DavidBLt34 Thank you again for drawing my attention to the 14-t saw blade. I have used it now in escapement W17. It works well, apart from the fact that you have to glue a bush to it to make it fit an axis tightly.
I did not know there was a wheel like this; thanks for the tip. However, I don't think it is very usefull, because the teeth are truncated with a very small slope. The leading edge of the teeth should be radial to make for a good Graham wheel. But I think it will do for W12.3 or WChr3. Success, Ben.
Thank you for the explanation. As with other of your escapements, it is not always apparent how the pendulum is being impulsed. I guess, as with most escapements (Lego or otherwise), the lack of big obvious hits of pieces leads to a more precise, and more efficient device. I am always amazed by your escapements. One of these days I will post a few of mine. They are less refined (think those big obvious hits) but they get the job done. Maybe you would have some advice for improvements.
Indeed it is difficult to see how the pendulum is impulsed. 'Dirtboy101' asked the same question; see my answers below.
Of course it is very important to disturb the pendulum as little as possible, which means short, preferrably non-sliding, contacts, with the contactpoints having approximately the same speed to avoid blunt collisions (the ideal clock would not give tic-tacs). Some of these requirements are approached by the chronometer (better in 'horolophile's then in mine).
No, becaue the pendulum is impulsed by the escapewheel, and the escapewheel is powered by a weight. The clock stops when the weight reaches the ground.
Well what I'm saying, and this doesn't apply to all clocks, is that the pendulum and escape wheel both use the weight in a sort of give/take relationship, but in this device, I fail to find an indication of what the escape wheel does for the pendulum.
Look at the lower middle of the video. Here the pendulum gets it's cick from the corner of a tooth. Indeed it is difficult to see, because the contact brick (pallet) is black, rather than red. You can see that when it passes the rim of the table. I did not have a red brick with a smooth face.

very nice! 5* but i think u had more going on than needed

That is true. See the very elegant solution bu 'horolophile'.

wouldn't the clock stop working when the pendulum ran out of momentum?

No, becaue the pendulum is impulsed by the escapewheel, and the escapewheel is powered by a weight. The clock stops when the weight reaches the ground.
