Abstract: The method includes locating three frame-positioning points on a faceplate panel and measuring the panel contour at at least four spaced points on a circle of given radius at a first spacing with respect to the frame-positioning points. Then, at a remote location, (a) a frame assembly is oriented on three reconstructed frame-positioning points which are in substantially the same geometric relationship with respect to one another as are the frame-positioning points on the faceplate panel, (b) signals are generated related to the position of the measured contour of the panel, and (c) the signals are utilized to position four mask supports in substantially the same geometric relationship with respect to one another as are the measured contour points but at a second spacing with respect to the reconstructed framepositioning points. Then, the contour of the mask is conformed to the contour established by the mask supports. With the mask conformed to the contour of the mask supports, the mask is permanently attached to the frame. A particular embodiment of the method also includes measuring the contour of the faceplate panel substantially at the center of the panel, measuring the contour of the mask substantially at the center of the mask and adjusting the second spacing to obtain a desired center spacing between the mask and panel when the mask is mounted in the panel while maintaining the mask conformed to the contour established by the mask supports.
