Abstract: An apparatus for fabricating wooden trusses includes a jig table composed of modular table sections cantilevered from supporting legs at one side and having a network of equally spaced indexing holes throughout the expanse of the table top. The wooden frame members making up the truss are assembled at their joints on pressure pads on the table top with the pads having pins which extend downwardly through the indexing holes. Air-operated lumber-locking devices hold the frame members together for fastening and are simultaneously releasable. A hydraulic wheel motor-driven lumber press is movable on a track along the jig table to press connector plates into the truss joints. The press has an open throat which receives the table top. A hydraulically actuated upper press platen overlies the full width of the table and a fixed lower platen underlies the table as the press moves along the table, stopping momentarily to press connector plates into the truss joints.
