description A drill string stabilizer has an elongated cavity formed in an exterior surface of the body. An elongated blade is generally disposed to extend from the cavity. The blade is extended or retracted by rotating a stud threaded on opposite ends with left and right handed threads. Rotation of the stud causes axial movement of slide blocks threadingly engaged to the stud. A follower and track between the body and the slide blocks causes the slide blocks to slidingly engage the body. The blade track is inclined relative to the body track so that the blade radially retracts or extends relative to the body as blocks are moved along their respective tracks by rotation of the stud. The position of each stabilizer blade is independent of the other blades.
