<p>A work bench has a frame (109) supporting a work surface (100) with runner assemblies (103, 120, 121, 122) which travel fore-aft in slots. The surface (100) is moved back and forth by handle (115) and screw jack (112). Slots (101) in the surface (100) expose fixed supports (123) with holes (110) which can be engaged in a selective position by pegs (108) of a fixed member (107). The surface (100) has holes (102) on opposed sides to receive pegs (106) of clamping members (105). The arrangement allows two work pieces, such as lengths of wood, of different widths to be worked on side by side and without excessive winding of handle (115) being required to accommodate the different widths. Thus a short screw jack throw is able to accommodate a wide range of widths of work piece by pre-set adjustement of pegs (108) of fixed member (107) in selective holes (110) on the fixed frame (109).</p> |
