Abstract
An apparatus for defining arcs of mixed radii on a workpiece includes a base, a first selectively extensible arm rotatably mounted to the base, and a second selectively extensible arm rotatably mounted to the first arm. An assembly for defining the arm on the workpiece is mounted to the second arm. An assembly is provided for releasably retaining the first arm at a first disposition for selective movement of the arc defining assembly through a first predetermined angular displacement to define a first arc with a first predetermined radius and to retain the second arm at a second predetermined position for selective movement of the arc defining assembly through a second predetermined angular displacement to define a second arc having a second predetermined radius.
