I have an old movement which I'm practising on. Despite my best efforts under my microscope, I can't separate the cap jewel from the end piece. I'm guessing this is not unusual for old movements with little servicing. What do people do to get them apart? Should I soak it in something???

Sorry...haven't got the means to take a picture that would be of any use. It looks like a regular enclosed cap jewel. I might give the IPA a go. Thanks for the suggestion.

I use a small ketchup jar, the single-serving ones you get at restraints with IPA and just drop it in, there is a good chance it will part as soon as it hits the fluid, if not, let it soak for 5 mins then give it a gentle swirl, after a few cycles of this it should part 🤞

If you have an ultrasonic - I put them in a bit of naphtha (lighter fluid) in a small container. I use old contact lens cases. A minute or two and they're free !

Take an old usb cable and cut it, remove one of the thin copper wires and you can use that to poke through the chaton and pop the cap jewel off.

    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
    • I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
    • No, I now realise it’s broken😥 ive looked for one online, but v. Expensive! im going to service as is, in the hope that  one turns up. Thank  you.
