ABSTRACT:
A guide bar assembly (10) for use in a T-slot (20) of a woodworking table (22). The assembly includes a top member (12) slidably disposed on a bottom member (14). The top and bottom members include cooperating pairs of wedge shapes (24) that cause a change in width (W) of the assembly in response to relative longitudinal (L) movement between the top and bottom members. Contacting angled side surfaces (30, 32) of the male and female wedge members (26, 28) provide area contact between the top and bottom members that functions to maintain the top and bottom members parallel during tightening of the fasteners (34) used to lock the assembly at a desired width.
