ABSTRACT:
A method and apparatus for providing a smooth radius on an edge of a sheared metal sheet are disclosed. The apparatus includes a heating element, such as an oxy-acetylene torch, and a supporting frame incorporating means for translating said sheared edge in predetermined relationship with said heating element. The method encompasses the steps of causing relative translation between a heating element and the previously sheared edge of a metal sheet to accomplish the reduction of said edge to a smooth radius.
