ABSTRACT:
In this invention the technology is provided for rod shaped conductor member fabrication in situ, in position, in the mass filter spatial configuration by growth through vertically repeated conduit mold formations, filling the conduit increments with to be rod material, and coalescing the growth increments as the rod length is achieved.
