ABSTRACT OF THE DISCLOSURE A method for forming a helical waveguide uses a deposit screen such as tape to prevent the deposit of unwanted material between the spirals of the helix. The waveguide is formed by electroplating of nickel on a mandrel. The mandrel has raised portions similar to a screw on which the waveguide is formed. The deposit screen is placed in the recessed areas between the raised areas on the mandrel to prevent the mandrel from being plated in these areas. This prevents the spirals of the helix from touching each other. The resultant helix is easily removed without damage to the waveguide or mandrel.
