ABSTRACT:
Method and apparatus for aligning a pair of planar templates on opposite sides of a planar board. The apparatus includes a pivotable open-book structure having a pair of surfaces which intersect at an inclined interior edge substantially paralleling the structure's pivot axis. Projecting from each of the surfaces, adjacent the lower edges thereof, is a pin for aligning matching edges in a board and template supported on the associated surface. When the structure is pivoted, an aligned board and template combination placed against one surface in the apparatus is flipped from that one to the other surface, exposing the other side of the board. The method of the invention proposes first, cradling a board and a template placed against one side of the board, with such cradling producing alignment of the two. The aligned board and template are flipped to expose the other side of the board. The aligned board and template and a second template placed against the other side of the board and then cradled to produce alignment between the board and the second template.
