ABSTRACT:
A method and apparatus for removing a waveguide from a mandrel. A helical waveguide is formed on a mandrel by electroplating. The mandrel has raised areas similar to a screw on which the waveguide is formed. A thin walled cylinder is slipped over the cylindrical mandrel and advanced axially as the mandrel rotates. A notch in the forward end of the cylinder acts to peel the waveguide from the mandrel. The cylinder then supports the waveguide in a helix as it continues to peel the remainder of the waveguide.
