A bit more progress. Just the crown to make, put on some dial markings, and a clean up and tidy.

 

Hands made out of a broken main spring. Hour wheel extended

Outstanding work Michael,

 

Truly impressed that you made those hands yourself but please tell, how did you manage to cut the spring steel to that accuracy, was it some sort of die or was it by hand. 

 

Looking forward to the next installment.

 

Cheers,

 

Vic

Hi Geo, I had not thought of changing from the raw brass and just buffing when needed. However, your post has got me thinking. If I do anything I think it would be gold plated, unless you have any other suggestions?

 

Hi Vic, they were done by hand, and I am not entirely happy with them, but time restraints means I need to press on. The method I used was actually quite easy, and it was as follows;

 

Cut an over lengthed piece of main spring and bend reasonably flat

Soft solder at the ends to a thin piece of oversized brass. I used 0.5mm as it is what I had for the dial base

Drill the hole where it fits onto the hour wheel

Then use a dremmel type tool with grinding disc to shape your hand to how you want it. The brass helps to grip it, and also to control the grinding.

During the grinding the hand will naturally come away from the brass. Grind off to finally release the hand from brass sheet.,

Tidy up as required with dremmel type tool and then sand on a piece of wet and dry, both sides.

I put the hands on a 2mm piece of brass sheet and heated from underneath. As soon as hands start to turn light blue take the heat away

Thanks for the info Michael,

 

Most ingenious and quite frankly they look ok to me, I wondered how you got them so thin.

 

Cheers,

 

Vic

    • 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.
    • Indeed. I would not attempt one. Here is my messy Sherline setup
    • 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.

    • These still seem stupid expensive for a bottle, but still £100 cheaper than than the Moebius ones. Anyone have any experience of these: https://www.cousinsuk.com/product/epilame-fixodrop-special-bottle-horotec
    • Yes, this is not a basic part. Here are some pictures of making one
