Re: Pulsynetic master clock: question about gravity arm roller.
I got rid of my (made by me) Sychronome, same idea and a clonk. Replaced with a Magneta PO36, almost silent. The dials do click a little, rather reassuring.

Re: Pulsynetic master clock: question about gravity arm roller.
Although I have master clocks from TMC, Synchronome and Magneta I'd not heard of Pulsynetic. Looks like an interesting project.
Just saw one of their slave clocks on a station that Michael Protillo was visiting on one of his railway journeys. I wonder if anyone remembersthe TMC "SPB", Short Pendulum Bob, master clock.It received it's sustaining pulse at random intervals as the pendulum lost amplitude. A relay energised sending a roller along a ramp which gave the pendulum a rather violent push. Not a brilliant timekeeper as I remember. Don m5aky |
