A wheel spindle flange has stud holes with soft surface hardness formed therein which permit non-rotational splines, studs and the like to be press-fitted therein with minimal press force at a centered press zone established between intentionally formed and dimensioned counterbores within the flange to minimize flange distortion and lateral run out of the spindle. Both crucibles have an outlet nozzle for the glass to be drawn. A slurry of finely divided ceramic particles is flowed through nozzles and formed into droplets under the influence of vibration. The device utilizes azimuthally-varying, axial, magnetic field perturbations.
