As for the coupling ring, I was already thinking that this would be a best solution.
I wouldn't fix it with expoxy though. Conductivity again 😉
Either make it a touch oversized on one end and screw in the body while frozen or just use a tiny dab of a thread locking compound - Loctite or similar.
Yep a ring... or cut the "head" and adapt it to a body. But I'll be able to see more clearly when I get my mic MkII...

Yes.
The process forms a hard, very resistant oxide(Al2O3) layer. Much more resistant that forms naturally. Which is also electrically non-conductive.
So... (it's not clear) do you NOT recommand adonized aluminium ? prefer brass ? (over other metals)

Do you mean that because of the 3 wires of the MkII capsule (plus / minus / ground) conductivity has to be from capsule to XLR thru whole body ?

These completly different techonlogies from 1rst to MkII version is getting me a bit headache (why did they change everything damn !)
 
Hmmm... I used to vape. Before the bases became ridiculously overpowered electronic laden devices.
Just a tube for a 18650 akku (or two) with a mechanical momentary switch.
I just went and dug out what is left of my stuff.

A brass tube 22 mm diameter, 2,5 mm wall thickness, threaded inside at both ends (regular thread), 19,5 mm inside.
Rings a bell?
Ready made and cheap (10 bucks or so).

The one I have left (photos) is too short but I had longer bodies.
I'd have to search my aging memory for the site net address and check if these are still aviailable.

Of course it'd need a screw-in XLR adapter/holder made. Which could make this whole exercise too expensive versus a body made from scratch.

Needs investigating.

Yep a brass tube like 22mm outside and 18mm inside to be machined correctly (not an issue). But the diameter of the capsule thread (19,2mm) and the diameter of the interface (18,8mm) leaves only 0,4mm of materiel which is thin (too much I guess). So back to a "kunction rig" maybe... So yes it needs reflexion and more investigations

(XLR can be held by a screw like most of the SDC and a dedicated hole in the body)
