Tips on removal, cleaning and reinstalation of fiddly cab jewels

[Nucejoe]

To keep fiddly cab jewels from leaving work bench, keep your left thumb on the cab as you unlock the spring, once unlocked hold the movement over a wide mouth jar, turn the movement so the jewel faces downwards, slightly tap the movemnt with a soft mallet so the cab falls down inside the jar to which you add your cleaning solution.

 I will post pictures showing the proceedure as sson as internet lets me.

I am trying to take close up pix and once posted will inform you to take a look . I hope this approach makes life easier for you all as it did for me. Cleaning in particulare yields astonishing result. 

As for English, have you ever counted how many languages there are to learn, we would have had to study all for universal communication.

Your vaccume cleaner approach is Universal.

Best wishes,     joe

The following aproach to safe cab jewel removal, if not entirely eliminate loss of cab jewels, will greatly reduce such incidents.Suitable for pre-cleaning.

The first picture is just to show angle of attack to unlock ETA cab springs , the actual removal is done inside a bag.

The second picture shows angle to lock the spring. 

Third shows you actually put the movement inside a transparent bag.

Stick sharp point into the bag to reach inside.

Remove the cab. The cab is contained in the bag, No where to fly out of the bag, you can then dump the cab in your cleaning solution container. 

Looking forward to no longer read someone lost a cab.

I used this technique in replacing the upper balance jewels on a vintage Gruen. While the shock spring was of a different style, called Trishock, doing it under a poly bag is a good suggestion. I didn't place the movement in the bag, but sliced a plastic bag up the sides to make it single layered, and placed it over the top. It worked fine. Thanks for posting your technique. Cheers.
