ABSTRACT:
A device that may be removably secured to a steel plate to guide a cutting torch in a circular path of a desired radius to form an opening in the plate. The device includes a cutting torch engageable socket, which socket is rotatably supported from a radially adjustable carriage. The carriage is movably supported from a circular track that is removably securable to the steel plate by permanent magnets. A radially disposed scale visually indicates when the cutting torch is at the center of the track, as well as the radius of the circular path through which the cutting torch travels when the carriage is rotated relative to the track.
