EtaChron stud removal

[Jon]

 

There is an old thread here that shows a YouTube vid of how to remove the EtaChron stud from the stud support, which I think is a bad idea, as there is too much downwards pressure on the stud support when using tweezers. It can be done that way, but isn't ideal, especially when working on a clone movement where the stud support isn't as strong as an ETA movement.

I put a lesson together for my class at https://efhc.org.uk/wordpress/index.php/centre-facilities/ to show how to do it without risking damage to the stud support and how to save over £60 making your own tools to perform this task (That's another lesson on hardening & tempering, if anyone is interested)

Here's the PowerPoint presentation. The video's within the presentation are marked in the top left hand corner of the slide 'Video'

 

Enjoy...

Very clear to understand lesson Jon.

I remember breaking the first etachron regulator I tried to remove with tweezers. 

Thanks for sharring.

Thanks Joe!

I broke my first one the same way with tweezers.

Wow, now that is neat. Very clear instructions and a novel way to manipulate the studs off the arms instead of using tweezers. Thanks you
