Machining the azimuth bearing box for Very Large Array (VLA) antenna #4 in Hobbs, NM, January 1976. The VLA antenna contractor was E-Systems, Garland Division, Dallas, Texas. They used a fabrication plant in Hobbs belonging to Structures, Inc. to fabricate the various steel antenna structural parts, and parts were then shipped to the VLA for final assembly.
