Torsional Pendulum Cutting & Clock Beat

The domestic tasks did not take too long and I managed to cut one side (the maple side) of the torsional pendulum on the CNC router.   I’m concerned that my ¼” ball end cutter is not as sharp as it should be as the surface finish was not very good, but nothing a few hours of sanding will not correct.

The clock continues to run well.

As there is not much news today, I thought you might be interested in more technical details on the clock.   Below is a summary of the teeth on each wheel and pinion.   This tooth count result in a beat (the time between ticks) of 6.3 seconds or 570 beats per hour.

The plan for tomorrow is to cut the other side (the walnut side) of the torsional pendulum.
