Building the P.90

The aluminum shutter for the P.90 is mounted in a precisely bored recess in the front panel of the camera. The assembled camera body is shown here mounted in the milling machine to perform this boring operation. The holes in the top and bottom panels of the body that eventually receive the hardware for transporting film are used throughout the construction process as a primary datum. In this case, a pair of 1 inch aluminum rods are mounted into these holes and are used both to level the face of the camera relative to the spindle and also to center the body for the positioning of the bore.
