ABSTRACT:
A multipurpose device for marking a workpiece which has in combination a component for setting the reveal between an edge such as trim molding and the edge of a frame, a component for setting an angle from 0.degree. to 90.degree., a component for setting a space between two solid members such as deck boards or pickets in a picket fence, and a component for determining the center of a flat surface such as determining the center of the surface of a board between 2 parallel edges. Preferably the device is a three layer laminated square with the middle layer being larger in the overall dimensions i.e., length and width, which in a square, are the same dimension, are greater than corresponding dimensions of the two outer layers such that the middle layer extends beyond the edges of the outer layers.
