5. A method for using a tuning slug assembly to tune a waveguide comprising the steps of:
creating a bore in a stem of the tuning slug;
rotatably disposing a non-threaded portion of the tuning screw in the bore of the tuning slug with a coupling assembly;
threading a threaded portion of the tuning screw through the slug cap;
turning the tuning screw to adjust the volume of the waveguide while maintaining the longitudinal position of the tuning screw within the stem of the tuning slug assembly;
forming an arcuate groove in the non-threaded portion of the tuning screw;
forming an aperture in the stem of the tuning slug assembly corresponding to the arcuate groove when the tuning screw is inserted into the bore; and
inserting a pin through the stem of the tuning slug so that the pin is at least partially received within the arcuate groove.
