If I started posting results pictures, I'd have ZERO time left for anything else! As for the conversions of N/AI, OM, C/Y, Petri, and Exakta mounts, I've documented them both here and on the MLFenses.Com forums, some with photos. But they're mostly simple enough that words suffice.
The N/AI-PK conversion (destructive): The aperture ring has "nub and arc" protrusions. I use a Dremel metal-cutting blade to cut those off, then a sanding blade to smooth the bottom of that ring. When the cutting blade has worn down to about 12mm / 0.5in diameter, I cut a slot about 1mm deep and wide and 5mm long in the N/AI lens base, for the PK locking pin to engage. Blow all the dust away, and the lens will now lock into a PK mount and will (safely) shot the mount pins, thus enabling CIF.
My workshop: In good weather, I work on a 2x6in back-porch railing. In bad weather, I put a 1x8 plank over my bathroom sink. Only the finest facilities, eh?
