I’ve done this kind of work (as an absolute novice) and its wonderful to watch a pro tackle these issues without breaking a sweat. This is great stuff Fran, thanks so much for posting. BTW, this applies to Mitutoyo test indicators too. I found out the hard way ;)

I love the transfers you're obtaining with this setup. Specifically, they look rock solid, with no jiggle due to pull down sloppiness. Most of the films are pretty neat, too!

Fantastic. As a watchmaker, it’s great to see Henry at work. It takes a lot of practise to tackle hairsprings without fear and dread. That’s a real gem of a movie - thanks Fran!
Wow, was 1974 that long ago???

That was intriguing, but very specialised. I wonder just how big an audience that would originally have had?
