A jig positioning system for use on a truss assembly table. The puck assembly 108 has a puck 109 positioned at least partially above the table top 105 with the puck 109 connected to a carriage 110 positioned at least partially below the table top. The puck assembly 108 moves along slots 118 in the table top 105. A threaded rod 102 extends through a threaded passageway 103 in the carriage 110, so, when the threaded rod rotates, the puck assembly moves along a corresponding slot in the table. A rod support member 116 extends along the length of the threaded rod 102 and is positioned below the threaded rod 102, the support member 116 contacting the carriage and, thereby, preventing the threaded rod from excessive sagging. A debris path is provided along both sides of the support member 116.
