An articulating support arm is used with a work station and has a central body with two ends. The inner end has a base pivotally connected thereto and the outer end has a platform pivotally connected thereto. The platform has an angled abutment that is integral with the platform and is located to be contacted by a slider that moves from side to side on a threaded shaft located on the central body. As the shaft is rotated, the slider slides along the abutment to vary the pitch of the platform relative to the body. |
