Hi all.

While following on Mark's training, on my first re-assembly of this test Chinese movement, I lost one of the three small screws from the crown wheel. Seems to be 0.6mm thread aprox 1mm long. I've searched through Cousins UK but there are so many options in there that i got lost :).

I could use a little help here, I am rookie, please  bear with me :).

 

Many thanks!

You haven't lost the screw, its only temporarily misplaced. Its there somewhere in the vicinity, you only have to find it. Big magnet !   Clear your desk carefully, the surrounding area and check the floor, its there i guarantee it.

yeah, I tried that :))))..the damn thing is so small, I gave up after a couple of hours. It might have jumped into a crack in the floor. I ordered from the Cousins this (attached).

I will to get some sweeping magnet asap!

You might be lucky, seiko and Chinese screws could be a different thread but always worth a try. A lot of folk suggest not having a carpet under your workspace, and i did used to agree with that. Try dropping a screw on a hard floor and see how far it travels, then try the same on carpet. If its in carpet its usually found, on a hard floor it can bounce and roll a good way from where it landed.

 If I had bought an assortment for every parts that pinged , I'd have a material house by now.    Go magnet.

I pinged a tiny screw last week and used a magnet and torch in every nook and cranny of my office to no avail. It's not a popular movement and parts are like hen's teeth, so I was prepared to buy a donor at a fair cost.

Today I was moving the other side of my office around, cleared a desk and there was the little sod. It had managed to ping around 4 feet, underneath a piece of equipment that lies almost flat on the other desk and rolled a couple of feet under it.

      Lathe motor advice

      By JseTay · Posted

      I sure appreciate your comment! I will look into one of those or maybe something similar. I of course will check your video to have a better idea.  by the way, that’s a beautiful lathe! Mine is a little peersless, but I just bought a Boley & Leinen that is on its way. That’s the one I am looking a motor for. It comes with a motor, but I want to replace it for  one that has a speed controller.

      Hello everyone my name is Tom and I and I am new to the forum and new to the hobby. I have always had an interest in mechanical watches and finally decided to pursue it. I’m going thru online trading and have purchased the basic tools to set up a work area. I’m really looking forward to learning and thank you in advance for all of your knowledge!

      Etachron regulation system

      By JohnR725 · Posted

      This conversation is becoming a very confusing. The etachron system is a very nice system for manufacturing watches. As you know it consists of two components the stud and the regulator pins. Beautiful thing of this system is you can open up your regulator pins center the hairspring and as you close the pins they will close equally on both sides providing you centered it in the first place. It's not like you're going to become closer to one side or the other as the definition of the regulator pins is a bit confusing it's not exactly a slot sort of. I'm thinking maybe a little eight reading will be helpful for you. Then the file name was changed by me at the US patent but the wording of Seiko may or may not actually be attached to it soared up? I just did that so I can find it in my files. Normally patents are in people's name if they work for a company the company name will be there you'll notice the person lives in Japan which is interesting as the name would imply that this is a Swiss product. Somewhere I think I have the patents for the stud and I believe that is Swiss like a lot of things their Japanese and Swiss and then the Japanese let the Swiss name stand as it seems you more popular in case as you read up on the patents of the regulator pins or pin will see and it should explain exactly how and why it works also why it's important to always close at an open in specific directions because the pins actually have a shaped to them it's very hard to see the shape as it's very tiny.   As a reminder with this system it's mass-produced. I wouldn't be at all surprised if they use cameras and computers to do all of the adjustments.  The meaning of this is that the majority of watches will function as there supposed to and do what they're supposed to do the system will allow us for some minor in tolerance and has more than likely as I said no human hand is ever touched those watches that's the way they left the factory and they work fine.
