Hi, guys I got there in the end after several attempts using a screwdriver and Rodico, I couldn't wait for the tool to arrive and was getting pretty confident handling the stud screw without it flying away. At first, I was using far too much Rodico, and then realized you only need the smallest amount inside the screw slot. Putting the cock back onto the movement also helped as it gave me more to hold onto while my shaky hand tried to align the screw wobbling away at the end of the screwdriver😁 Anyway, job done and I can move on. Thanks again for all the advice it's really appreciated for a beginner.

I'd be interested in a copy of this book if anyone has one they'd like to sell

You need to know at least the basics. Then the questions that You ask will begin to make sense. From what is seen on the video, the gear train and escapement look fine, but the balance doesn't rotate free. I can suppose that the thin gold colored shim that must stay under the balance cock is not in place. -

Yes, there are a lot of shapes and all of them are used in different cases. The one in Waltham A11 is one of the most spreaded and is what I have shown in the beginning. Of course, the radius of the final curve will depend on the distance between the hole in the stone and the regulator pins on the cock -

I just found these. They don't really grab my eye at the moment, but having seen the change in some of the watches on here, before & after, the results have been pretty impressive. https://www.ebay.com.au/itm/196382906131?itmmeta=01HXBSJJXDB5J6H916ARJP9PHE&hash=item2db9555713:g:REwAAOSwUNdmOYAZ&itmprp=enc%3AAQAJAAAAwOAlUO3a1pAUX60Y8gUeXMPriraj5e7rkBNH2EA6cIUH7kb7hzoq6jRmOsYOQazk9R%2FteDESr1e50Asabv2tbJyDM%2FVODtmrAScFS4jPhHdgu6Jvt%2BFuRGBijpTkPl4NiK%2FDGr6qztc1Ujb33Tt6YdaUztOH9R1y9XJbwjH0puPDy8m0ilYcal7Vphcp7d59DLtBliNnbqfxfWhxdia2xMRyHYFHzR0Rg7NqB1z4xQGMZb73MAG4QBiF9FMkrII88Q%3D%3D|tkp%3ABk9SR_KuyvnqYw
