I think there may be some misunderstanding about which lens I'm working with here....

You are using Nikkor 55mm F1.2 on Pentax K-S1 with adaptist right?

I have 3 Pre-Ai Nikkor: 55mm F1.2, 35mm F1.4 and 85mm F1.8 and 2 more Ais Nikkor: 24mm F2.8, 35-70mm F3.5.
I only used the Pre-Ai on my K1 because I worry the Ais' rear mount is too protruding and it might touch K1's mirror, anyway though it fits my K1 but it is not locked properly hence i am curious about adaptist.

So, did I understand your work correctly here?

my apologies - you seem to have a complete grasp of the project...

one note, however, neither of the two Nikkor lenses lock onto the camera body - one positive twist will take the lens completely off the body...

No need to apologies, by the way, even with adaptist it is still not locked like native K mount lens?

thank you

no - there is no locking of any lenses (other than K-mount) on the mount - every lens is held on the bayonet by friction....

I have yet to try an OM-mount (coming this week) or AR-mount, so we'll see...

both lenses are amazing at all points up to that end, and neither lens cost me anything even remotely close to serious money...

I am a bit disappointed in this, but I have a Nikkor that should be arriving tomorrow and am considering the Olympus option soon....

Did you try to fix the infinity focus by changing the AF fine tune*? This is a long shot, but might actually work, and would not take a lot of your time.

* i have no experience whatsoever with AF fine tune and MF lenses

I see where you're going, but I don't think that it will help if the lens physically cannot reach because of a limitation due to the registration distance/mount/bayonet tolerances.....
