Sorry that this question may be in the wrong topic, but whilst there is a good group of clever people on this thread (myself not included) do any of you have any ideas about A. - building (or buying) a MSF controller that can give me a switched relay output, say, every hour to run a synchroniser in one of my PO36 master clocks? and B. - any clever way of synchronising a master clock to such a device that isnt already fitted with a synchroniser.
I look after a small number of impulse clock installations (and am installing others) and could do with a way of them remaining accurate in a more automated way.

Hi ..Just a quick reply to kick things off. Do you have more than one PO36 or just one and are adding more and more slaves ?
Have you read up on synchronization and appreciate that it can mean several things. ie. Do you want to sync the "rate" of the pendulum or the indicated time and to what tolerance ? Roger

You want to fire up the 20V synchroniser that spins the right hand count wheel I guess?

a few years ago, a guy named Huw, a member of the Synchronome yahoo group, made some MSF devices that output seconds, 30 seconds, hourly and also a daily pulse (1pm) which I use to drive the synchronisers in 2 po 36's.


You can see the unit synchronising one of the 36's from 1:30 in the following vid.

I have no idea if anybody else has produced a similar unit since.


Many more GPO clock video's are available on my channel...

a couple of my clocks already have the 20v synchroniser, all i need is a device to drive it. What simon says is precisely what i'm looking for.
I'm also looking at creating something for those type 36 clocks not fitted with it without have to butcher anything. Essentially something that can reset the 30 sec countwheel such as some kind of stepper motor hidden behind. The idea was then to run the clocks slightly slow and have them synchronised to real time perhaps hourly or maybe daily. I have a few ideas how to do this, however it needs to be very compact and preferably hidden. The accuarcy could do with being as good as possible
