I did a drawing, took a while haha. you might want to check your own male adapters to suit fit for play, should be able to get down in the threads with very pointy calipers, attached a pdf as well, you will need to cut out a foam ring for that 6mmx1.8mm recess to shield from stray light.

The recessed groove starts from 6.27 mm from the outside edge the adapter .

The threads root is 41.26 mm on my 42mm male adapters i have which should give you 0.14 mm clearance on the t ring threads valleys when screwed into the t ring so it doesn't bind, you can just machine your own tolerance to fit.

you'll just need some short and long 3mm computer thumb screws or whatever size you like.

bore and threaded the second half and machined down the od. a little trick to work around those larger parts on small chucks or anything without a whole lot of material to clamp down in the chuck,just put in a m42 adapter and screw it in lightly,the load will hold it in.
this method was a lot quicker,it took me 20 mins to turn down unlike the first adapters facing method shown in the first post.

almost done!, the finish isn't excellent or the deburring( still learning)

edit: ohh i need a foam ring

What lathe are you using?
I've been puttering around with a Grizzly G0602 10x22 now for a few weeks and love it. (No DRO's on my machine yet, though...)
https://www.grizzly.com/products/Grizzl ... athe/G0602
I'm looking into the upgrades for it and studying YouTube channels for tips.

I have a small scale model of a scope and mount I'm working on... I'll put up a pic or two when i get home from work today.
Very nice job on the tilt ring!
I need to get some material for that project.
Cheers!

This is the lathe I have, opti is the brand name, I think it's made in Taiwan and may be a German company , it's an alright cheap lathe, does left and right hand thread, metric and imperial, no auto crossfeed. I think it's about the same size as yours.
