The size of the lens. Then put 2 prism together in front of each lens and rotate one until it is pointed in the right position.If the image is upside down, get him to grind 6 180 deg prisms, then put in front of the projection lens and have one end of each prism face each other. This will invert the image.
Make sure he puts florite coating on lens as to minimize light loss.
