ABSTRACT:
A reference chart apparatus for determining cutting angles of molding strips provides a tape housing containing a pair of tape coils. The top and bottom surfaces of the tape coils are imprinted with cutting guide charts providing miter angle and blade tilt cutting data for corner angles between zero and at least 180°. In addition, the housing defines three angled cutouts measuring 52°, 45°, and 38° respectively, for determining the slope angle of a given piece of molding. Each one of the cutouts is preferably colored with a unique reference color corresponding to an appropriate cutting guide chart sharing the same reference color. A housing clamp is also provided for removably engaging the housing, allowing the housing to be stored and used in a readily accessible area, such as on a miter saw.
