Restoration - Wires, bootlaces and heatshrink

Well the 46 is already being worked on. I have already moved the terminal strip and lable back down and reused the original screw holes. The title and the photo should explain how the 'new' wiring came about.

Re: Very interesting Paper on Clock Doc

James Kelly
 

Hi Ian 

You are welcome, there really were some talented clockmakers about, I wonder if they were hobbyists who made the synchronome variants, or professional clockmakers and repairers having fun in their downtime.
Perhaps we’ll never know.
By the way I have found the clock doc site a great resource and a wealth of interesting information, just hoping it continues to be available for all to peruse.

Regards

Jim

Very interesting Paper on Clock Doc

James Kelly
 

If anyone fancies a good read there is a very interesting paper on threnik Clock Doc site regarding four very unusual electric clocks from the
Scolnik collection the link below should take you there

Re: Help sought regarding T&N master clock

RICHARD ADAMEK
 

Hi Rob, 

I have a couple in the light bluey Hammer finish, both ex Dictograph and both with metal pendulums and cylindrical bobs


Original (i.e. German) documentation here http://wp.clockdoc.org/documents/maker-doocumentation/    in the T&N section, Google Translate is your friend ;0

I'll see if I can get you weight and dims of the weight tomorrow, beware there may be a reason for this being tinkered with, the one I have without programmer dogged father for donkeys years and eventually dogged me after he passed on, it would stop for no readily apparent reason in cold weather as the impulse to the wheel appeared to diminish, he doubled the coil voltage and added forcing weights to the remontoire but without noticeable improvement.

I eventually found this was due to the woven fabric insulating sleeve on the soft return wire that runs to the contact on the periphery of the impulse wheel, it had absorbed airborne oil over its years in an engineering works and this stiffened as the temperature dropped, absorbing what was a consistent impulse from the solenoid, a delicate laundry job has cured this, voltage and forcing weights are now back to original and it hasn't faltered in the cold winters of the last few years - it lives outside in an unheated building.

They were always Dad's favourite Masters (and having been serially a 'guest' of both Germans and Russians believe you me things from those countries got no quarter!) so I assume were head and shoulders less trouble than the earlier clocks by Magneta etc. and one of these is the clock his colleagues renovated and presented to him on his retirement from what was by then TR.

If the spring you are talking about is where the dial part of the drive train separates from the mainframe, this is the flrxible drive to the beautiful little contrate wheeled differential which allows the weight drive to pre load and both turn the armature producing the alternating minute pulse while keeping load on the going train of what is really a very nice mechanical clock mechanism.

Hope I can help with any other aspects if the same model or principle and feel free to email off forum as it is not entirely clear yet if and how much our Synchronome specific colleagues welcome or may tolerate 'other makes' traffic on what is when all said and done a single make group.

(A T&N has the distinct advantage that it can be sneaked indoors and set agoing without the self denouncing 30 or 60 second PERDUNKKKKK :)

Cheers & beers

Richard

Good evening,
I have just bought a 1970 metal cased T&N master clock and I think it will be a runner with a small amount of tinkering.
Does anybody here have one?
If so, would they be kind enough to tell me how much the small powering weight should weigh as mine is not original.
Also, I don't think the mangled spring that takes power from the back flywheel to the front movement is original, if someone has one would they be able to photograph the spring so I can see what it should look like, I assume it is in the style of a compression (biro) type spring that is used in torsion? Also what gauge wire is it made from?
Does anyone have any instructions in English please?
I look forward to any help provided.
Thank you
Rob

GPO type 46 joins the system

Edited

Made by Magneta in 1937 and then refurbished in 1966, this ½ second Master clock is already up on the wall under test.



Just needs the wiring changing to bring back it's original charm!



on the right is the more usual type 36which is one year older being constructed in 1936.

Re: Slave clock mechanism

Derek B
 

Hello Ian,

I can supply two of the late-pattern ‘slim’ Synchronome impulse movements in cases with lids, very similar to the one in your clock.  One has some rust on the case and the connecting flex between the coil and terminals has the insulation melted by careless soldering.  Easily replaced.  The other looks as though it has never been used.  They are Synchronome movements but have been fitted originally into GPO clocks, to work on their system, so have coil and shunt resistances to suit.  The combined resistances are marked as 7.8 and 8.0 Ohms, and test close to those figures.  They have the later 6BA nut minute hand fixing.  The ratchet wheel is fully crossed-out, so the minute hand will need a counterbalance.  I have a couple of hour hands that fit, but unfortunately no minute hands, so you will need to adapt the existing hands to suit.  These GPO movement are very adaptable and will operate with most half-minute series master clocks.

If you consider these will be suitable, you can have them for £10.00 each, including the hour hands, plus postage.  I can send them on approval, and if you can make use of them, then you can send a cheque in payment.

Best wishes,
Derek B.

Hi all,

 

Just acquired 3 Synchronome slaves,

 

Unfortunately in my enthusiasm I didn’t spot that only one of three had an impulse mechanism, the other two being electric

 

Does anyone have, or know, where I might acquire two 30 second impulse units

 

Many thanks

Hi Ian,
Although there are none today, EBay is worth checking as they come up on there frequently, usually around the £35 mark.

GPO was the acronym given for acquisitions in the later years, when nobody could be bothered to even sign you one over and stuff was disappearing hand over fist.

Re: Unknown clock ? home project?

Ian,
           Well  - a good question. An IBM I have is always within a few seconds a day. The IBM is the best clock i have.  I have 2 synchronomes and a Gents that are usually OK, until the next earthquake in NZ, which is once a month!. I have a PO 36 that is good. A Gents slave that is running on an electronic pulser, that is within seconds per year. A 1/2sec TMC clock that is a very busy movement and fun to watch, and is usually within 5 minutes. The remainder are either being worked on or in storage.
