ABSTRACT:
A method for orienting well casing and other tubular work objects of differing transverse dimension relative to each other including the steps of positioning the work objects telescopically relative to each other in such a manner that when the work object of larger transverse dimension is disposed in a substantially vertical attitude, the work object of smaller transverse dimension is pendantly supported gravitationally substantially to self center along a common axis with the work object of larger transverse dimension; disposing the work object of larger transverse dimension in a substantially vertical attitude; and mounting the work objects in fixed relation relative to each other. A device including a member mounted within the work object of larger transverse dimension defining a first plane substantially right-angularly related to the longitudinal axis of the work object of larger transverse dimension and a member mounted externally of the work object of smaller transverse dimension defining a second plane substantially right-angularly related to the longitudinal axis of the work object of smaller transverse dimension.
