The new MAMH-13 features a 25-3/4″ long x .844″ (21.43mm) diameter Upright Rod and Angled Extension Rod with two spring safety clips for holding one or two motors. It comes with the MABC-3 Base Mounting Plate and wood screws for attaching to any bench top. The angled extension rod height can be adjusted so that motors hang between 33″ to 38″ above the work area, as measured from the top of the motor, and 20″ to 28″ off to the right or left side of your work piece. These are the proper measurements for maintaining a relaxed curve to the flexible shaft.
