You don't have to cast the Moglice in place on the closer.  You could turn a piece of stock to the same (or slightly larger) OD, polish it, and use that as the male 'plug'.  

Could even make it solid stock with a threaded hole to use for pulling/pressing the Mogliced sleeve off.

And yes, Robin Renzetti's D-bit grinder was my inspiration, too.

I thought about this a lot since yesterday and arrived at pretty much the same solution. It is nice to have that idea confirmed by you, thanks for that.

oh and, the stuff seems to be relatively expensive.
If anyone has a project and needs a small amount (and is located in Central Europe), please give me a shout. Then I can send the rest after I am done, so it does not go to waste.

I bet Mark's (RotarySMP) collet closer leaks air too.  Maybe not as bad as yours, but likely needs a 'tune-up' after all these years.

According to Mark, it is not. And let’s see how complicated it will get, but I would not attempt this if I thought I could avoid it.

I am not sure if that is agreement or a dig at me. image missing /media/kunena/emoticons/unsure.png

Not a dig at all - just a tongue-in-cheek saying I found years ago.

Works better in person, since non-verbal clues (wink, wink) help both people understand how absurdly fatuous it is.

I finally found the problem with the threading. Should have found it much earlier.It’s the belt.

It gets chewed up. Opening the side panel, I found belt-colored dust, but the belt still locked fine, at least from the side. Looking closer showed that the teeth are broken up from the middle outward (see picture).
I found one tooth gap with some hard thing in it, so I assume that my initial cleaning when installing the belt was not very thorough and I overlooked that.
After cleaning that out and reinstalling the already damaged belt, I could thread fine. But I think this will not last long, so I ordered new belts and will install them after VERY thoroughly cleaning both pulleys.
It’s really typical for me that the solution to a month of problems is: “You should have cleaned the thing better.”
