  1. A quick look on ebay. I have found these clocks. Made in china and extremely poor in every way. Do not waste your money. A genuine French carriage clock would never have holes drilled in the bell. Hardly ever do they have a sweep second hand. The platforms are normally made of brass some are silvered. I can only assume the Chinese platforms are of a metal to look like it is silvered, they are very poor. If you are considering on purchasing a French carriage clock you can ask me for advice and I will whiling advice. I expect these links to disappear when there time is up on ebay. https://www.ebay.co.uk/itm/Vintage-Cloisonne-Enamel-Carriage-Clock-with-Twin-Bell-Chiming-Repeater/273257850972?hash=item3f9f6fe85c:g:2IAAAOSwJiJbFC2Y I have no idea who made this. It is very poor quilty https://www.ebay.co.uk/itm/Antique-Carriage-Alarm-Clock-Brass-Complete-Working/392052641707?hash=item5b48288fab:g:5OMAAOSwhHJbCq3s https://www.ebay.co.uk/itm/Vintage-Brass-Repeating-Carriage-Alarm-Clock-M-D-Ger/273257911846?hash=item3f9f70d626:g:CjIAAOSwSlRa7y8N https://www.ebay.co.uk/itm/Vintage-Cloisonne-Enamel-Carriage-Clock-Twin-Bell-Chiming-Repeater/182932078625?hash=item2a979a0021:g:F74AAOSwUwFaEvpc https://www.ebay.co.uk/itm/VINTAGE-REPRODUCTION-SOLID-BRASS-CARRIAGE-CLOCK-PLATFORM-MOVEMENT/202102035369?hash=item2f0e3853a9:g:V6oAAOSws6ZZ-3ff

  5. Thanks Joe. As you said, they are obsolete and many won't work on them because of there low value, but I think it is always good to get good at as many movements as possible. I've got many spares for this movement, but thanks for the offer. Much appreciated. If I need anything, I'll PM you. I don't know where to source hairsprings and balances for this, other than scrap movements, which I've been doing

  6. Excellent! A number of these popped up in the 404 Club recently. Pretty sure I ended up with two of them... Thanks to your minute wheel post, I now know better than to attempt them until I get a staking set!

  8. I think this is a front loader. There are 2 screw holes near the edge of the movement that suggests that there were movement retaining screws.

  9. I don’t like that the movement is there, but you could try inverting a can of “air” to release the cold liquid onto the ring and shrink it away from the case. once it’s out, address the tight fit. Either it’s out of round or oversized.

  10. I was working this 18S Pocket Watch and thought I had it fixed. Ran it for two days and all seemed well. Then I decided to look at the movement, I saw a very poor 30deg amplitude. So I thought it might the rubbing of the side of the hour wheel on the hole of the face. So, I removed the face and made the hole slightly bigger and that did not fix the problem. I took a closer look at the balance and saw the three of the hairspring turns were stuck together. I than demagnetize the watch and carefully separated the three turns. I started to run a lot better. That was part of the problem. The other part was the works not moving easily. That was fixed by oiling the minute, hour and intermediate gear posts. They had been previously cleaned but needed to be moved a bit. That fixed the problem and now the amplitude is very good and the hands and face look great. Again fun:)

  11. I whipped this out today. Mill, lathe and lapping all used to get it where it is now. Spent a few hours to save $17.00 so, it would be better to buy it... oh, well.

  12. Hey guys i have decided to buy a second hand lathe from an auction. At the moment i am still looking. The more i read the more confused i get. At first i will use it just to polish and clean up small parts and then i hope to move on to repairing small watch parts, (replacing staffs etc). The most confusing part is the motor. I like the idea of the pedal for speed control. But what power motor? Plus i do not have the money to spend a fortune on extra parts . Like what tools are really necessary ? What i have my eye on is a 6mm lathe or 8mm . What does that mean is it the size of the chuck? The metal it will hold? And on ebay someone recommended a guy who refurbishes old sewing machine motors. Do i need ventilation? What i need is for a hobbyist to make and fix small watch movement pieces or pieces you cannot now source. Any help appreciated. cheers gary

  13. A Texas Instruments TI 401 LED watch in slightly rough but original condition. I blew the budget (again) on this one, by a whopping sixteen pence. I pushed the boat out a little on this one, as I had recently been watching a couple of videos about the chip that powers this, and other similar vintage TI module based watches. Obviously for this low price, the thing doesn't probably work, but I'm fairly confident that I should be able to remedy that. You may find these two videos interesting. https://www.youtube.com/watch?v=CeXYZKg5jdo https://www.youtube.com/watch?v=KdLnEOwTO6E

  14. The sine wave effect on the timing machine could be an indication of magnetism. You're not going to get the right amplitude because you have no idea what the lift angle is. Then out of curiosity is it an English lever or Swiss lever because you're not showing us the full plate so we can see who made it? Then as you found out it's removing the balance wheel has issues. You can either unpin the hairspring at the holder but you have to put it back where you found it. Then yes it is, and that they hairspring is much longer than needed. Or you can move the entire holder with the balance wheel but the holder is really heavy and that can lead the hairspring distortion. The same as re-pinning the hairspring usually leads to hairspring not being perfect. This means you get to have the fun of straightening out the problem. In other words it gets bent at the holder and you have to reform the curvature correctly. It's not going to have much of a terminal curve like a modern watch. At least they usually don't a lot of the American pocket watches have almost 0 terminal curve. But still has to have the right shape if you want they hairspring centered. Then one of the things I would do is I would look at it visually to make sure it's in beat that's sometimes a clue to help you figure out where to pin the hairspring again.

  15. Yu can get rolls of shim, 6" wide by ... long. Also brass, which might be a good base for gold plate. Copper should be an option as well. Hands could be cut from the same material.

  16. Whilst cleaning out my father in laws attic ready for a new roof my wife found this little Siro Oris watch. The hair spring is broken and the balance staff pivots are broken on first quick look and not sure what else has gone but some hope it winds and the hands move.

  17. My mom handed me this Gubelin “Ball of Light” from the ‘20s and asked if I could do anything with it. It’s a manual wind 17-jewel movement that started up immediately when I wound it, so I’m not inclined to do anything with it other than find a necklace or charm bracelet to pair with it for my wife. Kind of cool looking, though.

  18. Below is a video of a Peltier cloud chamber. It gives you the ability to see charged particles emanating from a radioactive source. They demonstrate several objects including the source from a smoke detector and a radium lumed watch hand. It even picks up cosmic and environmental radiation. Fascinating, and pretty eerie to watch.

  19. Just to close out this thread concerning low amplitude, I finally got around to addressing the issue of too much lock. The pallet stones were probably not original as they were already set back into the pallet fork as far as they could go. I removed the pallet stones, ground down the back ends, reinserted them and applied shellac. After making some adjustments, the amplitude jumped from the initial 166 to 265 degrees.

  20. There's a lot of stuff out there on removing stubborn screws. Depending on the movement and the screw's location I've used Liquid Wrench(tm) and also Kroil(tm) penetrating oil. Under certain conditions alum will work but you have to be careful. It goes without saying that you strip down the movement as far as possible and then make a determination whether these approaches will be safe. Attached is a PDF with some more ideas. Hope this helps. Broken_and_Rusted_Screws.pdf
