A bushing assembly is provided including terminal ears coupled to opposed end walls of the bushing assembly. Each of the terminal ears includes an electrically conductive plate with a first terminal edge (1D) coupled to a bushing first end wall, and extending away from the first end wall to a second, free terminal edge (1A) and having a curved geometry. The curvature, 1/(2R), at any point of the curved second end of the slot is less than the reciprocal, 1/ Wo, of the smallest gap width, Wo, of both slot first open end, W.sub.A, and elongated portion, W.sub.B, where R is defined as the radius at any point of the curved second end.

The present one embodiment provides a method for manufacturing a bushing utilizing Cubic Boron Nitride (CBN) discs. The initial fabrication of the CBN discs involves selecting a suitable grain size of CBN powder, compacting the powder into a preliminary bushing shape, and sintering it at a sufficient temperature to bond the grains securely. Post-sintering, the CBN form is machined into the final bushing shape with precise tolerances. This method further includes forming holes in the CBN disc, assembling the discs into an array with the desired number of fibers, and creating a carrier to hold this array.

A spinner for use in manufacturing glass fibers includes a body having an upper wall with an opening therethrough, a lower wall, and a side wall extending between the upper wall and the lower wall. The side wall comprises a plurality of orifices, and the body comprises a metal alloy material and is formed using a localized welding method, such as a directed energy deposition (DED) method.
