I was just expanding upon something that you said? which is basically it's complicated. Then I'm not a math whiz but if you read the description of the items you learn that a lot of things influenced poise errors. Fortunately we only have to deal with the repair were not manufacturing. On the other hand if we were manufacturing and you are very clever with the formula you can just about make poise errors disappear. But that's of zero helped us repairing watches. Ā thank you. Somewhere in another group I went through the PDF and I was definitely not kind at all. Although there is something interesting in the PDF on page 47 there is a link to the Greiner timing machine manual. The Greiner timing machine manual is a really excellent reference as it assumes the watchmaker doesn't know what a timing machine is and it provides all sorts a really interesting and useful information including dynamic poising. So that's probably the most useful thing in the PDF. -
What happens if you fit the rotor to the framework off the movement? -
I found it lengthy and not well written. If interested in the topic: read Jendritzki. His writing is always clear and uncomplicated. Frank -
If you're ordering from Cousins then it maybe worth getting one of these also to match with the 0.8mm I-Ring.
