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.

    • Thank you @Mark. I only became a Patreon subscriber 5 or 6 months ago, but I draw so much value here. If you come up with future contribution or support opportunities, I will be on board.
    • Hi Mike I did a ships clock a long while ago, not a Hermle though and without getting the beast in my hands to refresh my memory I can’t recall the timing.  This doesn’t help I know but will start the grey matter turning.
    • Of course it will continue Richard.
    • I have stripped and cleaned a Hermle ships clock. It was just oily, no major faults, and I reassembled it, following my photos in reverse order. The time train is fine but the strike train will not play the ships bell strike for half-past. Ships bells play a four hour sequence for the 'watches' and play double 'ding' for the hour and the double dings plus one for the half past (eg half past the second hour is 'ding-ding' 'ding-ding' 'ding'). Sounds complicated but it isn't really. The strike wheel consists of pairs of bumps (for the ding-ding) and no single bumps. There must me some mechanism on the half-past that lifts the strike lever over one of the bumps so only one ding is played. When I get to a half past, it still plays double ding. I have a feeling it is to do with the lever in front of the rack (there is a sprung attachment  on it) and the position of the wheel (to the right) with the two pins that lets that lever fall, but no matter where I place that wheel I cannot get a single ding at half past! Please can someone help with advice on positioning so I can fix this? BTW Happy Easter 🐣
