John Wilding apparently had two publications with a design for an electric rewinder for 30hr long case clocks - one dedicated book, and a chapter in his "horological miscellanies" book.

Does anyone know if there is a difference between the two designs, or could recommend which one to track down?

Thanks,

Youra.

With the greatest respect to the memory of John Wilding ... it doesn’t look like there can be much detail in this:

Edit: __ There is one introductory page in the Horological Journal of August 1971 

plus four descriptive parts in the following issues

... I think that’s all you will find in the book [but I stand to be corrected]

.
It is a ‘Monkey up a Rope’ device, and uses Mercury tilt switches.

Try RiteTime publishing, they do all John Wilding books and are still trading, can be a bit slow answering emails

This book. It would be cheaper to employ someone to wind it for you at this price.

When I started work in the '70s one of the workshop planners was an ex clockmaker. In his apprenticeship which was pre WW2 he had to go round large houses in the neighbourhood to wind their clocks because ordinary servants couldn't be trusted to do it regularly or correctly.

At a mere twelve pages, that is presumably a ‘scarce’ reprint of the original articles.

With mercury tilt-switches, and geared synchronous motors, I suggest the whole project might be of curiosity value only. ... Oh yes, it also based on rope wind, not chain.

There’s a bit on electric winding in his turret clock book ,I used it as the basis for mine using more modern encased tilt switch

Thanks all.

I have access to the HJ issues, and I'll look them up next weekend.

I've also asked for the price list from RiteTime, and might get the Horological Miscellanies book assuming there are updates worth worrying about in it.

It's a rope wind I want it for - I'm building a clock at the moment with a Hugens endless rope winding arrangement, and don't really want to re-invent the wheel!

Cheers,

Youra.

I have that book on my shelves, a 1st edition hardback, and indeed just 12 pages, also along with Wilding's book on building the 30 hour clock the mechanism was designed for,

The articles in HJ are in the August to December issues according to the first paragraph in the book, so you can probably save yourself a goodly few quid if you have them, as MichaelG mentioned, the book is probably a collection of those articles.

For a huygens set up I'd investigate magnet on the weight (s) and Reed switches or hall effect. Feed the outputs to a flip flop and use the output of that to drive the winch motor

I bought original the book in 2002 from a Dutch books seller, cost 30Eur so always been pricey. I see one is available from Austraiia for around £30 delivered on Abe.

I made the winder around that time, see pics (sorry could not figure how to rotate) for my chain driven clock after working out a pully size to suit the chain pitch. Had some problems with the chain getting tangled jambing the motor so added a 20secs timer which unlatches a relay so it switches off after 20 secs, normally takes around 6 secs to wind. Altering the profile of the lead in guides solved that so the chain arrives flat at the drive pulley.

The book gives part no for the motors so used that to spec the motors. I had to to replace te strike motor with a faster one as the strike on a large no, ie 10 could beat the winding speed. I used mercury switches I had in stock from FLT battery chargers.

It's proved a real asset and althought it was a bit of a fiddle getting it right well worth the effort. Hope this helps

You know, once you are using an electric motor why stick with archaic mechanisms - just go for a stepper motor driving the clock through a remontoire spring and stepped by pulses derived from the pendulum?

Peter - thank you for the pictures - nice build!

Duncan - that's a possibility - I'm not exactly sure how everything is going to look just yet, and how I'll feel about routing the wires...

John - I understand your point - the task is to build a traditional clock (in most ways anyway...) - I want something up my sleeve in case the daily winding gets on my nerves, or I forget often enough for it to be a pain!

Rite Time have the "Horological Miscellanies" book for £25, which they tell me includes the BHI articles (with later updates) and a number of other articles which appear of interest, so I think I may well get that. I've located the HJ articles, but I think the other book content will make it worth it.

A friend has 17 clocks to wind every week and he uses a hand held electric drill. This has a key in the chuck with the "wings" cut off.

Winding gets to be a habit if you have clocks. I have 40+. 12 are 30 hour, most of the rest are 8 day with a few longer duration (one is year going).

Personally, unless the 30 hour clocks were VERY accurate, the irritation of them being wrong would far outweigh the hassle of winding. 30 hours get wound and put right every night on the way to bed. 8 day clocks get added to the winding and correcting schedule on Saturday nights.

It's just a routine!

NewsFlash for Youra:

The Horological Journal for June 2021 includes a very elegant design for a battery-powered ‘climbing weight’.

It uses five AAA cells, and the author states that they are replaced at each GMT/BST change

... which looks encouragingly efficient.

Michael,

Yes, thanks for that - I've just opened my copy and saw that too - alterations required for my rope drive, but some good ideas!

Good name too

Y.
