A machine is disclosed herein for effecting fabrication of structural members, or the like, the machine comprising a work station having tooling means, drive means for advancing the structural member longitudinally of said work station, and apparatus for properly positioning the tooling means with respect to a predetermined location at which tooling operations are to be performed on the structural member. The positioning apparatus includes an indexing arrangement, as well as gauge means which permits automatic operation of the machine, such that tooling means may be initially positioned with respect to a transverse axis of the structural member and then moved along this axis in short, controlled increments to and from the points at which the tooling operations are to be performed. The tooling means are positioned in response to the energization of a stepping motor controlling the short, controlled increments of movement.
