@Rallynumanair The pallets must have the shape of a hook, in which the toothpoints can rotate; an axle would be unreliable for that purpose. Moreover, for each pallet I use 2 axles, wide apart for one pallet, close apart for the other one. In this way the pallet arms can have the same pivot, in the middle of the pendulum and the pressure points are in the centerline of the pendulum.
@Lewissnicholls I don't think so. The Lego wheel I use has only 14 teeth (rather than, e.g., in the Harrison clock, 120), which makes the swing angle too large. Moreover, the escapement dominates the pendulum, which results in a non-harmonic motion. For precision (at least with Lego) you should go to the gravity escapements.
When the video loads, it says the video is 1:01, then it changes to 1:00

It looks like you used two 2x2 smooth plates. Why these instead of two 2x2 round plates with the hole for an axle in the center?

I really like your mechinisums, but are they ever accurate?

@BenVanDeWaal Okay cool, thanks for the reply. I'm going to give this ago.
