Bad start to 2017

It,s was my fault I left my workshop ajar last night and found our cat asleep on the window seal this morning. Had a quick check around the bench and nothing was broken and looked ok then !!!!!! I stepped on this wheel. It is from a very cheap (wife paid £5 for it at a fair) Enfield Smiths westminster chiming clock. I have posted a couple of pics of me trying to straighten the pinion and it is almost straight but I can not see how I can rivet the wheel back on as my punches are not deep enough to fit over the length of the pinion. IMG_1046.jpgIMG_1047.jpgIMG_1053.jpg

Good idea Mark yes I have one so I will give it a try. Getting the shaft absolutely straight will be the next challenge

What fun !!!!!



Lol

Good luck - I have every confidence you will repair. :)

Here's another idea, create a larger seat for the wheel.

Make a brass collar that you secure onto the arbor that has a wheel seat centered over the old position. The seat itself will be larger in diameter than the old seat to give it strength. Secure it with locktite. Chuck up the arbor and turn a new seat and a decorative back end.

Once its made  mount the wheel in a pot chuck to open the center hole to fit the new seat diameter. Stake it on normally.

Can't you drill the stake out. Its a very common movement as you know so there shouldn't be a problem.

I did think of that but I presume the stake will be hardened steel. I have found some Clock punches in various supply houses wondering if the holes are deeper to allow for the pivots.

Thats also a good idea but will I have the issue when staking the new seat i.e. the pinion is to long for my punch.

Well I suppose I could but the stake has to be domed & hardened. This is possible but a big job for a clock that cost £5. However if I can get the pivot absolutely straight I will try to solder the wheel onto the pivot.
Family commitments for the next few days but will keep you guys informed of the progress (if any!!)

I have a lot of Rebarb steel used to strengthen concrete. 1/2 inch would do it and its soft. It will turn quick in a lathe.

Do not need to harden it because you are staking brass to brass

Thanks family commitments stopping progress for a couple of days. Lots of options suggested with this but the priority is to get the pinion absolutely straight because other issues will surface if not.

Don't you mean rebar steel.

Just an update with this. I just could not get the pinion perfectly straight & also I found the wheel was also out of true. I did a an experiment for future reference & soldered the wheel to the pinion which works a treat so a useful exercise.

However I have now purchased a donor movement for the replacement wheel. 

What fun!!!!

    • That would be something! Which brings me back to;  
    • you think you're going to sleep tonight you're not, you're going to ponder the question of what makes you think those of the right parts?  
    • Does anyone knows what size case a need for a dial diameter 20.60mm?
    • Sounds like the story with my Rolex. Poor (expensive) job done by an official Rolex dealer with an "in-house" watchmaker, hence I learned watchrepair and did the servicing myself. Same story as I learned with the Omega 861, again poor job by an "in-house" watchmaker by an official Omega dealer. Once your watch goes through that back-door, you have no idea what is going to happening to it 🫣   Quite nice that they sent back the parts which had been replaced !
    • yes that's definitely not right at all. I have a picture one of my friends has a Omega coaxial there was having issues to lose asking me where he should send it. As that's a specialty watch I suggested the service center. When he got it back he sent me a picture so the replace the dial as you can see the hands the mainspring barrel and I think the price was really quite decent considering all the stuff they can replace. So I do know they do change the barrels but the other person I worked at the service center when I would ask questions and unfortunately I can't remember all the answers. I think a lot of the changing a parts is at the discretion of the watchmaker. Plus I don't know enough about the chronographs and whether that would be considered a vintage watch? I take some of the vintage watches may have been sent directly to Switzerland or another service center. Obviously with a watch like the one down below they probably have a infinite supply of parts is its relatively modern vintage stuff becomes more interesting even the watch companies don't have necessarily infinite supply of parts. But no matter what the watch shouldn't disintegrated six months that's definitely an issue.
