    Abstract

    The Raman Research Institute, Bangalore, India, has set up two radio telescopes (10. 4 m and 1. 5 m) for millimeter wave radio astronomy. Fabrication of these telescopes posed several challenges in metal finishing. Developing a coating for improving the wear resistance of the cutter used for dry machining of aluminium honeycomb, electroforming of corrugated horn with integral flange and circular-to-rectangular transition piece, and copper plating the 1. 5m FRP dish are some of the interesting problems that arose during the fabrication. The solutions developed for these problems are described.
