Sourcing a replacement abor, wheel, pivot

[andycar]

My grandfather clock cable snapped and resulted in damage to a 10 cog pivot and bent Arbor. Does anyone know where I can source a replacement.

That's a bugger, can it be repaired ? Dont know is pulling or cutting it off would be fun ? If it were me I'd be marking the pinion's position on the arbor...then see how easy it comes off.

The abor is bent and pivot snapped so thinking repair is hardly worth trying.

Someone may be able to assist further but would need details of the movement.

It's off a Welsh long case by watkin Owen of llanrwst c.1780

I think at that sort of age you'll be either lucky to find a donor movement or have to remake the part(s) yourself.

This parts are not completely replaceable. Well, depends on how old the movement is, but generally every movement was made for itself and nobody even thought that part from one would need to fit to another.

No problem to cut new clock pinion. The problem actually is it is big and a lot of steel must be cut by the milling machine, so bigger one is needed than for watches. Here I have shown how I have done on my general purpose lathe with home made lathe attachments.

Also possible to use another longer pinion with the same diam and leaf count and reshape it to fit

you forget Nev , you are among the elite of watchmakers , you can do what many many cant lol.

[nevenbekriev]

Actually I show that things are possible to do, just one have to find the way. This is the way I found when I had to restore that movement.

So what about making the actual part that's broken?

[rjenkinsgb]

Can you add some dimensions, to give an idea of scale? eg. distance between the plates, diameter of the wheel and pinion etc?

Well, new pinion needed to be cut. The first 12 pictures in the first link in my message show exactly cutting of a similar clock pinion. The others show the making of all the parts of the striking train that were missing

[andycar]

The abor is approx 75mm. The pinion 10 tooth 8mm approx. The wheel is not damaged. I have zero lathe equipment and skills. I was looking to pay someone to possibly remove the wheel and connect to a new abor with a new pinion. I'm in the UK. Does anyone know any machinists how could do this?

Always worth checking BHI accredited repairers in you area, look here for more information

Am I missing something as it looks like 7 teeth with 1 missing?

It is eight; look at the other photo, it's clear on that; three visible either side of the spindle, with two more or less in line.

I had a quote of £250 to repair the Arbor.....more than the clks worth

Rather expected TBH,  it is a very skilled repair and needs expensive equipment.

repair or replace seems like a simple question doesn't. Except replace with what exactly? The only time you can replace a part with a brand-new part is if the part exists. you would have to identify the maker of the clock the exact clock and find out if that particular clock maker actually even had replacement parts which is usually unlikely. Which is why most people in clock repair repair things.

I see part of my question is been answered except I wonder if they're still in business? Then as others have pointed out even if they were in business they would not have a replacement parts. So if they were in business they would make you a new part otherwise you would have to find somebody to repair the part you have now.

Labor cost is in no way connected to the worth of your clock.

[nevenbekriev]

Just to mention that lantern pinion can be made. This is much easier. Well, it will differ from the other pinions and will be in contrast with the style of the movement, but will work normally. If it is not so important, then may be it is the decision

[watchweasol]

Hi. I have thought up an unconventional way of effecting the repair yourself, using a pillar drill and filing , if you are interested pm me  and I will let you know.

[nevenbekriev]

@watchweasol, the repivoting is easy in such big wheels, but here the main problem is that one leaf of the pinion is broken.

[rjenkinsgb]

Can you post photos of the whole movement, or plates, with any makers marks or numbers etc?

 

[Neverenoughwatches]

Could pinion wire be made to fit if the correct size is available..then drill out the wire ?
