The apparatus comprises a pair of plates adapted to clamp the metallic member therebetween to define the annular chamber between the member and a cylindrical core. A ceramic funnel is secured on the upper one of the plates to communicate the melted bronze alloy particles to the annular chamber via the open end thereof.
