Abstract
Abstract An improved device for guiding a cutting torch on a metal surface which metal is a magnet attracting material comprises a magnetized base member and one or more guide members secured to the base member which guide members act as a template having a shaped surface for guiding the cutting torch. The device is provided with means for securing one of the guide members adjacent the edge of the base member and preferably means for holding or securing a plurality of additional guide members having different shapes or of different sizes when not in use. In a second embodiment, an assembly includes a support for holding the device of the invention on a pipe or other surface of revolution.
