Re: 1 second Regulator – state of play (By: Phil Burman)
It may be harmonic resonance. In the past I've mentioned that
things like where the crutch attaches to the pendulum can create
resonances in the rod. These can cause the pendulum to pull slightly
off frequency if they were close to harmonics of the pendulum.
If the harmonics were high enough, you could have a step like action
as the pendulum changes frequency.
