On 6/7/11, Collin Brendemuehl, discombobulated, unleashed: Here he is. http://brendemuehl.net/images/frank/frank1.jpg A shot taken with Frank. f2, perhaps slightly overexposed. http://brendemuehl.net/images/frank/berry.jpg The center. http://brendemuehl.net/images/frank/center.jpg This was pretty simple because the Minolta mount on this lens was in 2 pieces. Behind the camera mount is another support ring. Both the ring and the K mount had a rib which had to be milled off. Even so, the ring does need to be another 1mm thinner for infinity focus. Minolta used 8 screws on the lens mount. 4 attached the mount to the support ring and 4 went through the support ring to the lens body. I left out the holes for the 4 into the ring and just used the 4 longer ones that went through to the lens body. That's enough for this weight of lens. It might be easier to have a pro with a mill do the actual work on the mount and ring. Perhaps I will hire an engineer to finish it. Also, put a hold for the mounting screw near the red dot. That allowed me to attach to the lens body close to the center of the aperture scale for near-proper alignment. Still, it works for close stuff.

For some reason, the lens attached directly to a no-name K-mount extension tube, probably because of slack manufacturing tolerances on the tube. The lens wouldn't mount directly to the Pentax body. No infinity focus, of course, but that's not all that important with a macro lens.
