Taking apart the Micro-Nikkor-P 55mm f/3.5 Auto!!!

The non-Ai Micro (or any) Nikkor interfere with the Ai tab on the PK rings, doesn't it?

yes, it will 

[David H. Hartman]

The part that interferes, sticks up, can be removed. It's been a while but you go in through the front bayonet. The part rides on a race of dry ball bearings. It's not too hard to remove. It's devilish to reinstall.

Film at eleven...

If I remember I put a dab of grease on each ball bearing to stick them in place. Then after the leakage was secured I removed the grease with an electronics cleaner. There was no why I could figure to assemble it dry.

Even easier approach, get an E-2 ring. There is no aperture follower thus nothing to remove. It will mount on any Nikon camera and virtually any F-mount lens can be attached to this ring.

The 55 Micro will have stop-down metering.

A modified PK-11 tube is functionally equivalent to a short M2 tube, 8mm v. 27.5mn. I had a modified PK-11 and gave it to a school. I've been kicking myself ever since I bought a 55/3.5 compensating aperture version.

I now have two of those early 55/3.5(s). I wish I could add a chip to one of them.

They are easy to chip ...

I have a host of E2, M/M2- or similar rings adapter for special lens configurations. All chipped according to intended usage.

The picture below is a modified M2 for an Olympus 38 mm f/2.8 Macro lens. I have utilised the straylight baffle from an old M ring and it will be evident that the CPU integrates nicely in this setup.
