A wonderful narration of a complex mechanism! Great education for generations who have so much technology but can benefit from learning about early technology which enabled the Industrial Age. Thanks!
What a wonderful comment. Thank you and I do hope young people will learn to appreciate how brilliant these clock makers were long before computers and the internet were at their fingertips.
Have I understood it correctly that the minutes hand of the subsidiary clock is reset every hour at the pulse of the master clock? But how about the hour hand? Suppose every hour the subsidiary clock is 1 minute faster then the master clock. Then every hour the minute hand is set back one minute. But after 60 hours, it is been set back a full hour, at which point the hour hand, if not adjusted, is one hour too fast. So I suppose that the hour hand also has a slip fitting and that both the hour and minute hand stay connected witha 12:1 gear ratio. Is that so?
The hour hand will be geared to the minute hand so it would follow the movement of the minute hand. These clocks are easy to regulate to within a few seconds each hour so unless to correction is not received for many hours the clocks will not be off a full minute. If it is off more than 10 or 15 seconds+/- it will not accept the correction signal. They may get off by minutes or even hours but will need to be corrected manually.
Interested in the half minute impulse slave clock as I have a Western Union master clock with two different cams on the modified second hand one is 30 or 1mn sec points that do not lift off the other cam is 1hr contact that lifts ?
Hi Josh, There are several different cam configurations depending what the clock was originally set up to do. There are also different contacts. One may be for the hourly synchronization of subsidiary clocks. This one will be lowered on the cam just before the hour. The other one, hard to know. Alan
Great video and you helped me get my master clock syncing a couple of my other WU/SWCC clocks. I do have a couple questions? so what is the most clocks that you have sync from a master clock. I added a 3rd clock and the 3 volts are really struggling to sync. I know originally the master had a AC rectifier and I'm sure that kept the current proper. I did a set up where I did my 3 volt battery pack and then did a circuit like you show here and its working great other than now I have too many clocks trying to sync. Any solution? Also my rectifier says 6 volts not 3? any possibility that these needed 6 volts to sync instead of just 3?
Glad the videos help. I am pleased to hear that. Each synchronizing clock needs about 2-3 vdc to activate the synchronizer coils. You can get away with 2 synchronizers on 3 vdc but not more. You need to increase the voltage. Your 3 clocks would probably do fine on 6 vdc. I have my clocks synchronizing on a separate 24 vdc circuits. I have 7 or 8 clocks on each 24 vdc circuit. If you do not have that many clocks and are going to use 24 vdc just add more resistance to compensate.
@@SelfWindingClocks Thanks so much for the quick reply, that was my thoughts as well. But on NAWCC....they seem to be dead set that you aren't supposed to increase the voltage...... I'm sure the equipment used back when was different, and they probably used the same type set up as you are referring too. More Voltage for longer distances and the larger the number of clocks. I have noticed that the sync capability really dropped off once I added the 3rd clock. I also realized the type of wire made a big difference as well. The solid thermostat wire conducts the voltage very well, better than all the other low voltage wiring. Again thanks for the response, and its amazing to have a working syncing Self-winding clock system!
Thank you very much for the video that shows how does the subsidiary clock synchronized with master clock.
Glad the synchronizing video helped appreciate the process.

Thanks again. Any clock movement video from you would be interesting
Thank you Matt.
Amazing explanation and beautiful video! Another one on slave clocks would be awesome too! Thanks a lot for the clear and concise information!
Thank you Nazaret for your kind comment. Now that I know there is interest, I will do a video on SWCC slave clocks.
@@SelfWindingClocks that will be awesome!! Enjoining your videos and learning a lot! Thanks again!
Another great video. Nice to see how the process works. You've inspired me to get my synconizer working.
Hi Dan, Love to hear this inspired you to get the synchronizer working.

@@danieljeffries1134 The synchronizing coils should be connected in series.
