Abstract: The terminal portion of a winding end turn conductor which projects from the core member of a dynamoelectric machine is encapsulated in an epoxy potting compound by means of a casting assembly which comprises a detachable conformable pad, a plastic sleeve mold, and a portable vise. The conformable pad is fitted about the terminal portion of the conductor to provide a temporary barrier to axial flow of the epoxy compound during casting. The plastic sleeve is disposed around the terminal portion in a spaced relationship therewith and in an abutting relation with the pad to provide a barrier to the radial flow of the epoxy compound during casting. Clamping means such as a portable vise is fitted about the conformable pad and is tightened to establish a compressive union at the interface of the conformable pad and the terminal portion of the conductor to prevent leakage. A pair of spring members hold the sleeve in abutting engagement with the surface of the conformable pad during the casting process.
