OK ... now we turn into the MOST DIFFICULT procedure associated with this adaptation. It has to do with connecting the aperture setting ring to the bronze channel "fork" that is attached to the aperture setting cam within the lens body so that one can set the aperture more or less properly. For this you need to take the object at the upper left apart. This will result in a shower of tiny ball bearings falling on the work area. What you need out of the remains are the finger that extends down into the lens body and slides within the aperture setting "fork".
