Tool time
Curtis Ellison readies an aluminum 'sacrificial' plate in a horizontal mill where he is preparing to machine clamps that will be used in the engine test cells. Mr. Ellison is a tool maker with the 76th Propulsion Maintenance Group Repair and Development unit. When engine maintenance workers in the Oklahoma City Air Logistics Complex need parts or tools to get their jobs done, they turn to the engineers and tool makers of the R&D unit.
