A work piece positioning device which has a table upon which the work piece is supported is disclosed. The table is rotatably mounted on a sub-assembly which is tiltably mounted on a frame such that the work piece can be positioned in any desired predetermined attitude. Two worm gear systems are utilized for positioning the table, one for the rotating action and one for the tilting action. Each worm gear system has a worm gear, a tiltable worm and a locking mechanism. Once the table and work piece are in the desired predetermined attitude, the locking mechanisms are actuated, locking each worm to its respective worm gear.
