Bent Arbor And Broken Teeth

[transporter]

Struggling on this one guys, im in the process of servicing a smiths empire 3 train westminster chime grandmother clock movement, all is stripped and cleaned and awaiting a few bushes to be done ( easy part)

The hard part is trying to find a new/replacement part, its the first wheel of the going train, the movement suffered a broken mainspring at some point in the past, this in turn bent the arbor and wheel and bent 5 teeth on the wheel, 2 of which snapped off.

I have my local watchsmith searching for a replacement but he's having a hard time trying to find one. It's got 62 teeth and is 41mm in diameter. I will get the pinion to pinion measurement in the morning, i haven't got the part at the moment somi will measure between the plates tomget anear as damn it measurement.

Have any of the members here possbly got one lying around that would be willing to sell so i can get this movemnt back together and working again.

many thanks for any help in advance

Done abit of surfing on the net, ( not the ocean, to messy at the moment) and have come across a gem of a book called clock making in in england in the 20th century ( i think ) anyway i have finally found the same mark on the rear plate in this book as i have on this movement, it dates from 1938-1940, its a pre war Enfield K1 chiming grandmother clock movement rebadged as smiths empire for marketing purposes.

so the golden question now is where to find Enfield clock spares for a K1 movement ????

[clockboy]

Spares are always a challenge & I dare say you have looked at timesavers or there is another guy who,s worth emailing John Wardle see his web site below:

​There are guys who specialise in making parts & they advertise in the BHI mag every month. It depends on how much your budget stretches as they are not cheap.

[transporter]

I,ll be nonest the budget isnt bottomless mate, ive an mx5 that needs restoring by April and a job lot of seikos on the bench awaiting my attenetion aswell, cheers for the links, cousins i use already for alllmy watch parts, but I'll try the others youve given me.

[oldhippy]

You have a budget so have a look on ebay for an old movement. Now if it had come to me I would have been able to make the parts if no replacements could be found. The steel in these movement is quite soft so it won't take much bending.

[transporter]

Oldhippy, im actually looking at poossibly replacing the broken teeth on the wheel and having a look at trueing the wheel, as for the arbor would you reccomend using heat to help bemding it straight again?

No I never used heat for this. You could fix it in the lathe gently turning it by hand and tapping it with a wooden mallet until it was right. It takes time but its cheaper then making a new one. With the wheel the broken teeth can be fixed by finding an old wheel with the same teeth, cut out what you want and cut and file the replacement part and solder, if done correctly after cleaning you should hardly see the join.

[transporter]

Oldhippy, many thanks, after some surfing ive read abit on straightening arbors and yes you are correct not to use heat, im going to have to collect the part from the shop in the next couple of days and i will have a look at what needs to be done, fingers crossed

Here's an example of this type of repair, not my work but the work of a previous repairer,  there are also some good youtube videos showing the technique. :)

That is a very poor example. As I said when it has been completed you should hardy see the repair. I would expect an apprentice with very little know how to do better then that disgusting mess.

[oldhippy]

atimegoneby. That movement is a french strike with rack striking. Made of good brass and very high grade steel.

Glad it wasn't my work, I would have been ashamed of that !  but as you say , a nice French movement  circa 1900.

I'll be honest guys ive never done a repair like that before but I'd like to think that I would be tidier than that, im kinda making my mind up here to attempt the repair myself, i dont want to have my local smith waste to much time going through his stash of old movements trying to find me a part for what is a non profit let alone paid job on what is really a cheap mass produced clock movement.

If you haven't replaced teeth before, why not try with some old stock and replace a single tooth.

I'm in for a penny in for a pound on this one, im good with tools etc and there seems plenty of info on the net on how to do it so I might aswell have a go and see how it ends up.

I wish you luck. Let us know how it goes and take your time.

I have seen this repair in books & I seem to remember seeing it in a BHI mag.  As a matter of interest do you use silver solder for extra strength or is normal solder sufficient.

[transporter]

I'm going for normal solder, with some flux obviously, I will check on the net to see if any specific solder ie the contents will be needed.

Normal solder is all you need and a little flux.
