A method of forming ports in a fuel burner wherein the ports are formed in a single stroke employing a tool having a plurality of punch members arranged in an array corresponding to the configuration of the burner body that may be a complex shape. The burner body and tool structure are supported for relative movement toward and away from each other. The tool structure and body are moved toward one another to form the array of ports in the burner body in a single relative motion. This motion is terminated before the material punched by the tool is severed from the burner body.
