Has anyone recommending dismantling binoculars ever done it?

I haven't seen anyone recommending it. However if you have to, you
have to.

They are extremely difficult to collimate especially to more than one
person.

No, they're a piece of ****. They're designed for easy mass production
and they're not particularly sensitive to mis-alignment anyway. 10×
magnification? It's hardly rocket surgery.

Apart from, I think, a huge pair of East German border guard jobbies,
I've not seen any binoculars that were adjustable to collimate anyway.
The lenses are centred, and the rest is down to trusting the lens
mounts to be machined accurately. Re-assembly is just the reverse of
dismantling.

Besides which, what does "collimate to more than one person." mean?
Collimation is collimation, it doesn't vary between people. Even for
your pointy little head.

Lidl binos can be collimated, they have various adjustments.
Most are the same, you just don't have a clue what to look for or what it
means.

Google for conditional collimation and you might learn something to fit in
you flat, empty head.
