Abstract
A single apparatus handles drill steel to position the drill steel pieces for tooling and repair by a lathe. Drill steel needing repair is accepted on rails of the apparatus. A drill steel piece to be repaired is moved along the rails and is moved onto hydraulic drive cylinders. The drive cylinders raise and move a first end of the drill steel piece into the lathe. Support cylinders raise to support the piece while it is being re-threaded and repaired by the lathe. The drive cylinders reverse to remove the drill steel piece from the lathe. A pivot raises to capture the drill steel piece and rotates the piece to present a second end of the piece to the lathe. The drive cylinders and support cylinders likewise present, support, and remove the second end to the lathe for re-threading and repair. A unitary frame supports the rails, the drive cylinders, the support cylinders, the lifting/rotating pivot cylinder, and the hydraulics of the apparatus.
