13. A method of coupling a drill head to a member, the member including a first wall, the method comprising:selectively attaching the drill head to an upper attachment portion of an adapter, the adapter including a lower housing portion having a first outer wall and further including at least one actuator having a first portion slidably mounted to the lower housing portion and further having a second portion configured to expand from the first portion in a direction perpendicular to the first outer wall;
positioning the adapter over the member such that the first wall is received between the second portion and the first outer wall; and
activating the at least one actuator such that the second portion expands away from the first portion toward the first wall and clamps the first wall against the first outer wall.

1. A support frame assembly for aligning a tubular member relative to a drill head, comprising:a base;
an object support member having a first position and an elevated second position, the object support member configured to retain the tubular member;
a plurality of pivot arms operatively connected to the base and the object support member; at least one of the pivot arms having an actuator for moving the object support member from the first position to the second position;
at least one spring operatively connected to one of the plurality of pivot arms to move the object support member relative to the base in a self-aligning manner, thereby enabling self-aligning movement of the tubular member relative to the drill head to provide self-alignment of the tubular member with the drill head.
