Thread: John Wilding 8 day Weight Driven Wall Clock
02/01/2017 20:08:57

Hi Dick,

Thanks for the information. It's just as well I asked for help instead of charging ahead on my own. You are right about me using the old (1990) book. I have made the lantern pinions. I'm the same as you with regard to a mixture of imperial and metric.

Hi Stephen,

I'm at the stage where I'm starting to look at the pendulum and escapement and I have a number of questions.

1) Is the arbor which supports the pallets and crutch 3/16" diameter with 3/32" pivots? I can't find any reference to it in the book.

2) I can't find any dimensions for siting the pivot hole or the holding screw holes in the back cock which supports the arbor. Are these not critical?

3) I can't make head or tail of the crutch. Do you have any photos of your one? Is the angled bit at the bottom of the crutch separate from the shaft and if so how is it joined. What are the two 10BA holes for? How does the top of the shaft connect to the collet?

A lot of questions I know. Wilding's book is driving me crazy with the lack of dimensions on the drawings and the poor explanations on how to proceed. This is supposed to be a hobby - i.e. fun! Not much of that at the moment.

Regards,

Alan C.

Hi again Steven,

I've just noticed on your 3rd photo that the collar on the right of the centre arbor doesn't rotate in the side plate. I've reamed the hole on the front plate 0.150" for this arbor. Have I got the hole on the front plate wrong as well?

Thanks Steven. That's just what I was after.

I'm not sure how far I'll get. I faffed about for a week getting ready to start drilling the pivot holes in the plates, and then made a mistake on the very first one! I drilled the centre wheel pivot hole 3/32" instead of 1/16". I think I'll leave it and add a collar to the shaft to hold it in place.

If I do manage to finish it I'll maybe put together a couple of general assembley drawings and post them for others in the future.

Hi Dick. Have you made the shell? If so, did you use silver solder to join the two halves?

Thanks for all your comments.

Regards,

Alan C.

Hi,

Has anyone built the John Wilding weight driven 8 day wall clock?

I started one 10-15years ago and struck a problem so I set it aside to think about it. I'm getting old and if I don't get stuck into it now, I may never complete it. I think I've resolved the problem I had initially, but I realise I'm not sure where all the bits go in relation to each other as there are no GA drawings in the book and the photos aren't much help either.

I'm particularly interested in pictures looking down into the clock showing the escapement and pendulum supports.

Alan C.

Hi,

I've been mucking about with steam engines for the last 10 years or so and have made about a dozen or so of them. They all work OK but my only attempt at making a Stirling engine (Manfreds 2-90M) failed so I suppose my skill level is only average.

The first project I made was actually Gallileo's Escapement by John Wilding which I successfully completed. About 12 years ago started on his 8 day weight driven wall clock. I struck a problem and put it aside to have a bit of a think about it. A couple of weeks ago I started on it again and have realised I'm not sure where all the bits go in relation to each other as there are no GA plans in the book and the photos don't show the crucial bits.

Up till now I have been a member of the HMEM website but they don't deal with clocks much. I see that this site does so here I am.

Regards,

Alan C.
