I now have two separate movements where I cant seem to remove the ratchet wheel from the arbour ... both are solid. I wondered what my options might be for removal  - I am concerned about ruining the screw head or shearing it through too much force. Any suggestions gatefully received. On one I have to date tried using the tipof a soldering iron to introduce heat and left it soaking in both isopropyl and an easing oil each for a few days to no avail.

I have come across ratchet wheel screws which are reverse threaded, like the crown wheel screws. 

It's worth trying to turn the screws a fraction in the opposite direction you are trying to go, as it might break the stiction - and you might discover they are reverse threaded.

One movement is an AS 984 (so I assume not reverse threaded - the one I applied heat to and soaked is a Trench Watch movement so will see if that is reverse threaded.

The trench watch movement was indeed reverse threaded ... made that error before so feel a bit of a numpty .. the AS 984 wouldn't be a reverse thread would it?

I just checked on a 984 in my parts bin. The ratchet wheel/arbor screw IS reverse or left hand threaded, so clockwise to undo.

 Sooner or later I might be called Mr Coca- Cola here, for having prescribed Coca-Cola as penetrating solution for loosening screws all along. 

Give the ratchet screw a 48hr soak in Coca-Cola، try loosening before the coke dries.

I've never tried it as a penetrating solution, I must give it a go. I just not keen on drinking too much of the stuff - your nuts might fall off 🤣

I'll stick to beer and whisky 🤪

      Thyme tea

      By HectorLooi · Posted

      I wish to share my experience with thyme tea with everyone. Six months ago when I had my second bout of Covid, my chest was so congested that breathing deeply hurt. Coughing was pure agony. And with a 40°C fever that comes back every 6 hours when the level of paracetamol in the blood falls, I was willing to try anything.  Then I saw this video on YouTube and I decided to give it try. I drank a cup of the stuff and went back to bed. When I woke up about an hour later, I coughed up a golf ball sized lump of greenish-yellow phlegm. And almost immediately, all symptoms suddenly abated. 24hrs later, I was feeling perfectly fine. I repeated an ART test and it was negative. I started recommending it to some of my friends and many of them found it useful, although some claimed it had no effect. I had another round of Covid last week. I tested positive on Thursday and although the symptoms were very mild, I drank a cup of thyme tea just to play safe. And by Friday evening all symptoms were gone. I repeated an ART test and it was negative. If any of you read this, try it out the next time you get Covid or the flu. Let me know your experience with thyme tea. @watchweasol, you might like to take note of this.

      Listen to that little voice in your head

      By ManSkirtBrew · Posted

      Why is it when that little voice says, "This is a bad idea," we always want to talk ourselves out of it? I had the low blood sugar jitters earlier, but insisted to myself that I'd be able to oil an especially tiny cap jewel on my friend's Omega 1001. With lots of concentration, I nailed it. But when I put the hole jewel on top, it was too much oil and it squoze out everywhere. It didn't spread on the cap jewel much thanks to the epliame I'd applied, so it was more than it looked like from the top. Back in the cleaner, dried, re-epilamed, dried. Time for a second try, but now I was more shaky even than the first time. "This is a bad idea," my brain told me. "Take a hike, brain," I said as I watched the oiler jiggle into my microscope's frame. And just like that, the jewel was a tiddlywink and flew out of sight in the blink of an eye. With a strong UV flashlight and the waste of a lot of time I did find it on my desk, but that's some stress I didn't need in my day. So friends, listen to your body, and listen to your brain when it tells you now's not the time for precision work.

      I dont think Hector means there is an issue with the hairspring at the collet, only that the collet is not centered over the jewel hole. You can check this by unmounting the hairspring from the balance and recentering the collet with the balance jewel. If the coils remain undisturbed then i believe it unnecessary to dismount the collet and only adjustment at the stud is needed to bring the hairspring to shape. If any of coils have been accidentally bent then reshaping of hairspring separately would be required.

      @HectorLooi Thanks.  I do have a microscope. But no camera to show what I see in it.  You are correct that some coils overlap. In particular the outside one where thr regulator pins go  overlaps the previous one. I will try your suggestion.  I am surprised that there is an issue with the collet as I don’t see how I would have messed that up.  I didn’t think the impulse jewel is damaged as I can check it in the microscope. I meant that when I put the balance I am always wondering if I managed to set it correctly in relation to the fork.  Thank you all. So I think I will take @HectorLooi advice and note that the hairspring needs fixing and go practice with my second ST36. In any case this one also has the setting lever screw broken in the setting lever.  I think I’ll also order a dial, case, hands and strap to make a watch out of that second movement.  I see a bunch of them on AliExpress or eBay.  Anybody has recommendations?
