Abstract: A template device and method for guiding a marking implement in marking circular lines upon a workpiece and, interchangeably, guides a router in its cutting engagement in following the marked circular lines. Comprising a planar member having paralleled opposed major faces, a guide plate includes a plurality of evenly spaced guide holes between a plurality of unevenly spaced guide holes. All holes are the same diamter, being aligned in the central portion of the guide plate. All holes interchange as pivot, radii marking or cutting guide holes. Bearings with shafts including center holes receive bushing that firmly contain and center a variety of workpiece penetrating and surface adhering pivot anchors and a variety of marking implements. The bearing shafts are insertable, rotatable, and easily removable from any hole within the guide plate.
