Hi Ian Does topping off require any specialist equipment? Howard

I would add that where the count wheel has been damaged it may be necessary to set the jewel slightly deeper so that it properly catches the lower teeth. This will mean that the higher teeth show some

Interesting use of computer mouse pad, I will have to keep one back before they become obsolete! My clock doesn’t have the gravity stop but all suggestions welcome and would like to see clock with nic

The return spring is a spiral spring around the arbor that hooks into the frame, same as in your video. Yours looks to have extra weight added via brass nut and bolt which maybe necessary with earlier

How much bounce should you expect in the gravity arm, I am occasionally seeing a double impulse where it fails to latch. Reducing the current to slow things down gives unreliable advance of the pilot

If someone has spent 5 hours on it without success then there must be a problem! And the obvious has probably already been tried. But as per Ian’s advice depth of gathering arm is critical, if you wat

Yes that would work but I thought the piece of kit would be useful and fun to have. Regards Howard

Thanks, i wanted to bench test the distribution board away from the master clock. So was looking for easy way to generate a signal. The Arduino sounds like it needs other bits with it and some knowled

Is an impulse driver something to buy or something to make? For someone with no skill in electronics buy would seem sensible but what would be appropriate to go with a Synchronome distribution board?

Hi pallet design drawing is on NAWCC clock forum website dated 17 sept 2007 posted by fdew

Thanks for sharing your experience refurbishing, I guess Pt is used because it's harder than silver, Perhaps a silver nickel coin could be used for the contact pad. One source of childhood pocket mone

Hi What is the correct fix for warn contacts, the contact on the gravity arm is pitted without a lot of meat remaining and on the armature warn down close to the thread. I have not tried the clock and

#2054 is very much standard, coils green, finish crackle, buffer yes, case oak flat top, pilot no 1. type small movement. I've no idea what Roller wire/plate refers to! Clockdoc website interesting re

You are right, connected to power supply unit which masked the problem but again it stopped overnight. Investigating further found gap across contacts had increased. Having set the gaps at normal room

My Synchronome #2054 ran for 45 days before latch failed to reset. Setup is transmitter and pilot at 11.5 ohms running at nominal 3 volts and 280mA from 2 Energizer Max D batteries. Thought it might d

Maureen Dillon book was an excellent Christmas read. Up until the 1920's electricity in the U.K. Was supplied by 100's of Companies or privately generated, either AC or DC, varying voltages. Houses we

I wonder what the level of illumination would have been in a house of the period? Even a property such as Cragside with electric lighting from around the 1880's would be dimly lit compared to modern s

Moving on, the Contacts between armature and gravity arms don't line up with contact being made just on the edge of the gravity arm point. I can't see any adjustment to bring the point of contact to t
