ABSTRACT:
The present invention provides a woodworking worktable assembly which may be used in combination with a multi-purpose woodworking tool. The worktable assembly includes a worktable having a work supporting surface and an elongated slot formed therein. A guide insert is positioned within the slot and includes a horizontal base portion and opposing side arms for guiding a guide bar portion of a miter guide. Lip portions extend inwardly toward the center of the insert from the upper ends of the arm portions and serve to prevent the miter guide from being lifted vertically away from the slot. In addition, the base of the insert is spaced from the lower portion of the slot by foot portions extending along the length of either side of the base amd fasteners are provided at the center of the insert for drawing the base toward the lower slot surface. Thus, by tightening the fasteners such that the base is drawn toward the slot surface, the arm portions are caused to pivot inwardly such that the tolerance between the insert and a miter guide received therein may be adjusted.
