Took another step today... My jewelling set arrived and looked fairly decent even though a couple of items were missing and if/when I need them I will have to get a few reamer replacements as at least one looked more like a corkscrew... :-) But the very nice thing was also that the seller had included a bunch of glass tubes with balance jewels and guess what, one of them was exactly the one I needed, diameter 0,9 mm & hole 0,11 mm! And furthermore, this dimension was one of the few obsolete ones in the Cousins list. After running through Mark's video on the topic again I managed to push the jewel in place. I have attached a photo of the new thing and just have to hope I got the depth precise enough as it wasn't entirely easy to feel when the pusher was sitting exactly on top of the old jewel and note the micrometer setting. Will now continue with the cleaning and assembly and a few prayers that the movement will eventually run. I'll keep you posted on my further challenges... Sent from my iPad using Tapatalk
