Disclosed is a tool set for use in forming the components of a decorating nozzle from sheet metal. A tool-mounting plate mountable on the headstock of a metalworking lathe is configured with concentric grooves into which circular ribs on the tools can locate. Transverse formations prevent relative rotation between the tool and the tool-mounting plate. A method of forming nozzles comprises rolling a metal blank onto the surface of a forming tool as the tool is rotated in the lathe. Successive tools are used to achieve the desired shape.
