Worked on my first fusee watch today. By far the most difficult part is dealing with those brass taper pins, looking for a better way.

I worked on my first fusee watch today.  I'm happy to report that I didn't snap the chain.  I'm waiting for some taper pins to come in the mail, whenever the Royal Mail sorts out that malware attack.

But removing the existing taper pins is what really was a pain in the butt.  Some of them had almost nothing to grab onto to remove.  Some were slotted in a way that made it difficult to maneuver my tweezers to grab.  But specifically the fusee cone is what was the most difficult. 

The taper pin that held it together was filed flush on both sides so there was nothing to grab onto.  I ended up finally being able to drive it out using one of my smaller screwdriver blades as a punch, but it was hard to try and keep the thing upright on its edge while I hammered it out.

What are your recommendations for removing taper pins?

I don't suppose the pin in the fusee was copper color?

Then the fruit of the brass pins in the plate I use a 15 a or something equivalent cutting tweezers. I'm not trying to cut the Pin but you can reach in with cutting type tweezers and grab the Pin as long as you're careful you can usually pull the pin out because otherwise as you found trying to pry it out from the backside is very difficult if not impossible sometimes.

I used old tweezers split in half and shaped them to fit so I could get behind the narrow point of the pin and push back. You will find adapting old tools helps a lot when coming across new problems. Fusee pocket watches are for experts in horology certainly when it comes to anything with the escapement.

Now that you mention it, they did seem to be copper in color.  Though it's hard to tell since they're so dirty.  Some of them were undeniably brass, but this one I could envision being copper.  I will look onto cutting tweezers.  Thank you.

We all have to start somewhere! 🙂

The reason it's copper color is because it's supposed to be made out of copper.

I'm attaching an image out of  Donald DeCarle's book on practical watch repair.  The pin is supposed to be  copper so it can be driven out as it explains the book. Unfortunately it's not always copper because people don't have the book and it ends up being all sorts of other things.  And sometimes it's barely tapered at all so you have to try both sides to figure out which way it might be to get the thing out..

Thank you for the image.  I've had the book for some time now but skipped over the chapter since I hadn't done a fusee watch till just now.  Completely forgot it was in there haha.

Giving something delicate a whack with a hammer seems to be a way to potentially destroy something, so if possible, I'd like to avoid that.  I'm sure I could always rig up something simple to hold the fusee cone while I gently tap it out.

When reassembling, does the taper pin need to be filed flush with the arbor?  Because at least with the one I'm working on, the arbor rests in the pivot, and the area below the shoulder never contacts anything.  So why make it harder for future diassemblies?

I don't think it really matters as long as it doesn't hit anything. It probably doesn't even in real life have to be copper as long as somebody get it back out again some day. Then sometimes even if it doesn't hit it's also recessed which doesn't give you a lot of room for sliding and stuff anyway.

With some there can be a little grove for the pin, besides you do not want an unsightly  pin to be sticking out, it should also be tidy both ends. After all these years in horology I have never found or learned any tricks when it comes to repairing these pocket watches.

I think those slight imperfections are what give the watch character. 🙂 

Especially on old watches, the hand-engraved stuff connects you with an art spanning hundreds of years.

You should look at some of the very early pocket watches and clocks. You will see engraved and saw piercing on parts that are not visible to the naked eye. You might ask why did they do such things when you can’t see them. The answer is because they could and they took pride in their work. Unlike to day with mass production and the I don’t give a f**k if it works or not as long as I get my money.

This is why have always liked early English watches there always beautiful. Somebody took a lot of time and effort into making something very pretty.

Ok I think this topic has run its course.

I think there's another way that you can do this? Just as you're supposed to give thumbs up for answers you like I think there's some way as the person asking the question you can mark that an answer has been received. But as I never ask questions I don't know how to actually do that.

      Watch won't run after installing new balance for Seiko A-201 sportsman

      By rph952 · Posted

      I installed the donor pallet fork and now the watch is running, but only for 10 seconds. The lower side of the pallet fork only seems to go into the hole when I add the bridge. A visual check shows lower and upper are properly seated. I'll check the hairspring.

      I get that, but you're making unnecessary work for yourself. Resign yourself to having to give the movement a final clean and lubrication once you've fixed the problem. You probably won't need to redo the balance or the barrel in any case. The oil captured between the hole and cap jewels will still be good even if you've had it in and out of the movement half a dozen times.

      Thanks, some great advice. I have to go over the train every time I refit anything as each wheel has it's own bridge (cock?). They have a tiny amount of play so you can tighten them down in slightly different positions. This changes the gear mesh. I went through all that when I first started having issues with it. Movement works isn't fitted at the moment and nor is the seconds hand. The only reason I'm cleaning it every time is because each time I assemble it, I lubricate it. Mainly because you have to remove the balance wheel and hairspring to oil the top balance jewel. It's a pain so I always live in hope it will be going together for the last time. As the top one has to be oiled, so does the bottom one. Then I may as well do the train wheels.... I could just do the whole thing dry, but if it works, I'll still have to disassemble the balance again and it's always a risk. The hair spring is pinned, the cap jewel screws are underneath (stupid design. To be fair, the 3 separate bridges is a stupid design too).   I'll play with it more tomorrow and gather some more info, pics, and maybe some video.   Thanks for all the advice.

      It's not great, IF you did the test without the pallet installed. Assuming 18000 beats per day, 25 seconds is 125 beats or about 62 oscillations. You should get 100 or more. If the pallet was in place when you did the test it means nothing. Either way, this is not the principal issue. I was going to mention that I recently worked out that I get much better pics with a loupe held in front of the phone camera than trying to shoot down the microscope. I use a 20x loupe, but try with whatever you have. The roller jewel (or impulse jewel) could be an issue, particularly if it is loose, but this is also not the main issue. Get some clear pics so you can ask the experienced members here about it after you have addressed the main issue. Nothing in the escapement explains the rapid deterioration you're seeing 20 minutes after winding. That suggests an issue in the train rather than the escapement. The failure to self-start after it has been running a while confirms that power is not getting to the escapement. If it was me, and I was confident I had eliminated the barrel as the source of the problem, I'd be looking further down the train. I'd first make sure the canon pinion was out to eliminate the motion works as a source of the problem. Also make sure the centre seconds pivot is removed, if it has one, or the seconds hand if it has sub-seconds. If that didn't make a difference I'd then work my way through each wheel starting at the centre wheel. Is it sitting level? At the right height? Does it have just enough end shake? Does it have excessive side shake? What happens if you touch the upper pivot with a piece of pegwood with just a little bit of power in the mainspring? What about the lower pivot? Once I was certain there was no problem there I'd move on to the third wheel, and so on all the way down the train. Just because the train runs freely with the pallet out does not mean it has no problems as excessive side shake (for example) will only be an issue when the train is under tension. Finally, I advise you to stop re-cleaning until you have fixed it. I know the temptation, but it's just a distraction. You need to be systematic and methodical.

      Independent battery chime in mantel clock?

      By HectorLooi · Posted

      If you short the two blue wires together, does the unit chime? I have a similar chime unit that is designed to work with a quartz movement with an hourly trigger switch.  I'm not aware of any movements or chiming units that chime quarterly.
