It's been a long trip but arent't they all when you're breaking new ground. All my attempts using an M42 adapter ended in failure when trying to focus to infinity. A new approach was needed and here it is.
This conversion is pretty simple but you do have to disassemble and remove part of the aperture controls from the lens to the camera, grind down the lens housing at the rear and a locking divot must be drilled in the rear plate of the contact. The tough part will be making the flange.
What we, my machinist and I, did was to create a set of blades that mount where the old contax blades mount. The mounting is easy but getting rid of all the conflicting protrusions took some time. At this point I have a working flange and making copies should be fairly easy in the future. Very little can be done on the lathe and most must be done on a mill or by hand.
Here are some pics.
