ABSTRACT:
There is disclosed herein a gauge for aligning opposite points within opposite surfaces of a normally symmetric body. The gauge comprises an elongated guidebar disposed above and upon the symmetric body. The guidebar is also perpendicularly transverse to the plane of symmetry of the symmetric body. Also included are left and right calibration assemblies which are slideably disposed upon and within opposite halves of the guidebar, each of the calibration assemblies themselves include an X- and Y-axis joystick connected, in each axis, to respective means for converting linear physical displacement of the joystick to corresponding electrical output signals. The gauge also includes means for electrically expressing and comparing the respective left and right X-axis output signals and the respective left and right Y-axis output signals, wherein, through the use of reiterative output-to-input feedback adjustments of points upon one of said opposite surfaces, the respective left and right sides of a normally symmetric body may be, by such reiterative adjustments, brought into accurate alignment with each other.
