Abstract: A drive shaft assembly for a portable lathe includes a first hollow shaft and a second shaft axially aligned with and telescopingly received in the first shaft, for permitting an effective length of the drive shaft to be altered within a limited range. The first and second shafts are also rotatable relative to each other. Opposite ends of the first and second shafts have uncovered joints including mounting flanges attached thereto, and a locking device is provided to lock both first and second shafts relative to each other after they have been adjusted to a desired axial and rotational orientation.

Abstract: A method of removing a pin from a hole including a) drilling a first hole of a first diameter in the pin a selected fraction of a length dimension of the pin and attempting removal of the pin; b) if the pin cannot be removed, drilling a second hole of a second diameter smaller than the first diameter an extended fraction of the length dimension of the pin; and c) removing the pin.

Abstract: An electrode of an EDM drill is aligned in at least two planes by positioning the electrode at a plurality of positions and determining the distances between the rotary center of the EDM drill and a plurality of points on the workpiece surface co-linear with the longitudinal axis of the electrode. By comparing these distances, it can be ascertained whether the electrode is aligned with the workpiece surface in a given plane. If the electrode is not aligned, an angle of rotation needed to align the electrode with the workpiece surface can be determined empirically.

Abstract: A method of repairing a turbine rotor wheel having an annular damaged dovetail includes removing the annular damaged dovetail from the turbine wheel, leaving a wheel body having a rim. A forged ring is welded to the rim and dovetails are formed in the forged ring to accommodate turbine bucket dovetails. The welding process including preheating, welding, and stress-relieving are performed while the rotor under repair is disposed in a lathe for rotation about a horizontal axis. The turbine rotor repair is accomplished from start to finish without displacing the rotor from the lathe.
