Hopefully this may be of use to someone. It is a cheap and easy way to make the two tools needed fpr post or collet adjustment and it certainly works. I decided to create the posting as a PDF and hopefully most people will find it ok. Making a collet or post adjustment tool.pdf Cheers, Vic

Greetings! Just joined the forum and completed my first ever overhaul. It's a little vintage Waltham mechanical, circa 1960's to my understanding. Certainly nothing very valuable dollar-wise, but being my first successful overhaul I'm proud of it. :-) When it arrived the old oil had it so gunked up nothing would even move. A good thorough cleaning and a little fresh oil and she's ticking beautifully! Sent from my iPod touch using Tapatalk

The problem with that particular video is it's showing the final product of hours of work. Then is your vibrating tool is missing the base? I wonder if it came this way? If you look at the video there's a a heavy base with a lever that you push to get the thing to rotate. Then there is a major problem with using the tool today the supply of hairsprings. August 2007 the British horological journal has a article "Anthony Randall FBHI gives a brief history of Balance Springs". So the article gives a history talks about hairsprings and explains briefly about the CGS numbering system. The other reason for the article is there are no more generic hairsprings being produced by the Swiss. So in the early days multiple companies producing generic hairsprings purchased by watch manufacturers who vibrated them for their own watches. So today there's only one swiss hairspring company producing hairsprings for specific calibers only no more generic Springs. Or the watch companies themselves produce their own Springs for their specific watches. Then to understand hairspring vibrating start to finish I have a link below to an article written by a student in a school learning watch repair. the amusing aspect of the article written 2003 is the remark made about endless supply of hairsprings. in the same school today I can't quite remember the details but I think they only do one balance and very limited number Springs to learn with or they just don't do it. Conceivably at some point in time there will be no more vibrating Springs taught at the schools as a have nothing to vibrate. http://www.tp178.com/jd/watch-school/6/article.html Then a must-have book for hairspring vibrating as it explains in detail about the CGS numbering system how you use it to pick your hairspring vibrating precision timing all those helpful things to make use your tool.

If you use the correct movement holder, you can keep pressure on the hammers while pressing on the hands and ensure absolute zero is obtained. Without doing this the hammers are only held by spring pressure and the hearts may move slightly when positioning the hands. Using the correct holder also ensures that you don't dislodge the lower jewels when firmly pressing on the chronograph hands.
