Abstract
The subject invention relates to an improved steady rest for use in a portable heavy-duty apparatus for machining large rotary work pieces. The apparatus includes a heavy-duty portable base and a cutting assembly for cutting the large rotary work pieces. The steady rest includes a pedestal releasably secured to the base. A jaw support is mounted on the pedestal. A pair of C-shaped movable jaws is mounted on the jaw support positionable in a selected attitude for receiving the rotary work pieces. A bridge connects the upper ends of the jaws to form a complete circle around a portion of the large rotary work piece. A roller is mounted on each of the jaws for rotatably supporting the rotary work piece. A brake is mounted on the jaws for releasably holding the rotary work piece.
