ABSTRACT:
An adjustable pattern adapted to be utilized with a cutting machine having a drive motor with a drive motor output shaft and a cutting element associated with the drive motor so the cutting element follows a cutting path generally following movement of the drive motor. The adjustable pattern includes a base pattern having a surface defining a pattern path which is connectable to the cutting machine; a first drive post having a drive end connectable to the drive motor of the cutting machine; a second drive post; means for movably connecting the second drive post to the surface of the base pattern defining the pattern path so the second drive post moves along the pattern path as the second drive post is rotated; means connecting the first and the second drive posts so that rotational movement of the first drive post rotatingly drives the second drive post; and means for selectively varying the distance between the first drive post and the center of the base pattern thereby selectively varying the cutting path defined by the movement of the first drive post as the second drive post moves along the pattern path.
