I googled a bit for ”hole closing punches” and the method appears mainly used for closing worn pivot holes in brass clock plates.

Which is obviously a quite different thing than working on a tiny roller from a wristwatch movement that , as pointed out, may be made from a much harder material and may split rather than give away.

If there’s experience out there from this specific item, please chime in as I’m interested in arguments in any direction.

I have pinched a roller table hole to reduce it’s size when I was making a balance staff and shaved off a bit too much material. As was said, just take your time , punch it a few times then test it and punch it again. I only punched it on the jewel side without an issue. Try not t screw up the jewel, but if you do, you may need to shellac it back in place.

      Message board problem

      By Mark · Posted

      Looks like the kind of message that occurs when there are routing issues between your local network and the remote server the site is living on - there can sometimes be 20 or 30 hops and when there are issues some of those hops become unavailable temporarily for some people but for others where there is a different path being used the issues are not manifest. Another explanation, and this used to happen to me a lot with my ISP, is using the ISP DNS servers on your device or router sometimes is not as robust as changing to a public service such as 1.1.1.1 or similar. I was having a terrible time watching Youtube a while back - changed the DNS on my Apple TV to use 1.1.1.1 and problem solved. However, these issues tend to resolve themselves fairly quickly.

      As mentioned by the other members, it’s a dismantle job clean and inspect the solder joints. It’s an older generation using the paxolin pcb  not the glass fiber ones.

      Hi  in regard to your questions,   The springs should ideally removed from the barrel but to do this you need a mainspring winder that are quite expensive for a one off. Or you c a make your own see Google “ joes mainspring winder”. I have made two and they work well, you will also have to source some tube for the retainers. the gathering pallet cann be removed using levers ( mini crow bars) again I made my own no problem. the case can be glued using evostick wood glue but bind the case together to close the crack. When solid you can use wax sticks (used for furniture) melted and rubbed in to cover any blemish left. best to clean the case and then use bees wax to polish, a bit of elbow grease needed  do not clean the dial with anything other than warm water and a couple of drops of mild soap. Try on an inconspicuous part first. There is a product called MILIPUTTY in various colours on eBay that can be used on cracked enamel dials depending on how bad it is .
