Abstract
An improved point detector sleeve includes a tube portion and an adjustment portion that are integrally formed with one another as a monolithic member, whereby the point detector sleeve is substantially free of joints between the tube portion and the adjustment portion. The tube portion includes a beveled surface formed thereon, and the adjustment portion includes an internally threaded region formed thereon. In accordance with one method of manufacturing the improved point detector sleeve, a first end of a cylindrical pipe formed with a cylindrical cavity is cut with a rotary cutting tool to form a substantially cylindrical inner surface. The rotary cutting tool advantageously closely follows the cavity to form the cylindrical inner surface without the rotary cutting tool radially “walking” away from a central longitudinal axis of the pipe. In another embodiment, the pipe receives therein an insert having an externally threaded region and an internally threaded surface.
