I needed to service a really old camera lens as the focus ring was all but seized and I had to remove 7 of these tiny little monsters just to get deep enough to remove the old grease that was basically glue after all the decades.
Unfortunately I couldn't get all the way in as I needed a specific tool to get the last internal ring off so that I could fully clean it.
But the focus ring now moves so that's a win, I'm hopefully going to find the tool I need so I can fully service this tiny monster though. Which means I'll have to dig into it again.
Edit: Of anyone knows exactly how to disassemble a Vega 7e camera lens I'm all ears BTW, I'd love to see how it's supposed to be done.
Edit 2: I was able to work the grease into the focus rings, unfortunately using calipers didn't help much in terms of getting deeper into the lens in the way I needed to.
If I understand correctly - you have trouble removing a screw ring. There is a specialized tool for that:
Buuut, if its not too deep in the case - you could unscrew it with a caliper.
