In theory, 0.01mm would be enough to let a nose piece slide in, but I still wouldn't rely on it for consistent results.

Thanks Joshua, that's why I usually tell my friend there is no tolerance. I did however have a hell of a job getting the Vixen adapter out of my big lumpy thing I've decided to redesign and make significantly lighter along with the ability to thread filters in at the front. That's after the mill and lather are both properly set up and I get money for more tooling, starting with a good vice, clamp set and parallel bars (yeah, I'm going to become a gymnast at 63, LOL).
I notice all of your stuff has a very professional finish, do you anodise them yourself?
That's something I've yet to play with, I'm sure I have black food colouring here somewhere and most of the chemicals needed (or was it just vinegar? I forget).
I've so far chosen the lazier route of self adhesive black felt in everything.
I used to run zinc and anodising baths at an electroplaters back in the day when cyanide was a major ingredient in the tank. You don't skip the two or three water rinses between the sulphuric tank and the tank with cyanide.
I used to leave work with some bad headaches back in those days (early 80s) but considering I've had chronic migraines on a near daily basis for over 50 years it may not have been the job. I never pushed a broom without hosing the dust down first though.
How is the RC project coming along?
I did a 2 year fitting and machining course at a TAFE over 20 years ago one or two nights per week along with a few days per week doing fabrication engineering and another night doing hydraulics and pneumatics. I had a lathe till 15 odd years ago but moved and had no space to keep it (an old Myford M7 from memory). But, in saying that I don't consider myself having a high level of skills, I forgot too much.
I am however going to look into a CNC conversion for the milling machine when I have enough money to buy the bits and pieces and figure it all out.

Purchased with lathe and recently purchased separate table. I'm guessing far from the quality of what you work with.
We all have to start somewhere.
