That's not what I'm seeing. It looks to me like he sets the
diaphragm tension by screwing the inner ring tighter.

No. Watch the video again. The guy is going very slowly and carefully,
too, to make it easy for you to see what is going on. If you look at
the Feilo factory they are just slamming these out about once a minute.
This guy is going a far more careful job; you can see exactly how the weight
works.

Ok, you mean at about 3:08 in the video? Ok, I was referring to
about the 1:50 mark in the video, where he tensions the mylar in the
rings by screwing the inner ring tighter.

But again, using the weight of the rings, to set the diaphragm
tension, isn't rocket science! Any factory could do that! The
mylar just needs to be reasonably flat against the electrode.

I don't see the big secret of capsule construction, other than
having a 2 micron accurate lathe.
