Nikon on Pentax K

I heard somewhere that older Nikon lenses will mount on a Pentax camera....the register distances are pretty similar (Nikon is like .5mm longer) but I have a hard time believing that the mounts are physically compatible.

Is this true?

Have not tried it, but it certainly looks like a worthwhile pursuit

Yup, there have been other reports of success since that thread.

The Nikon F mount fits, but not solidly. I wouldn't recommend doing it on expensive lenses.

Roxsen also sells a Nikon F-to-M42 adapter that won't allow infinity (it is thicker than the 2mm difference between the M42/K-mount and F-mount) but I'm thinking about using this adapter and adjusting the infinity focus point on the lens. This way I don't have to do mount surgery to get them to fit solidly on the Pentaxes.
