ABSTRACT:
A mandrel assembly for a portable lathe is disclosed having a clamping system which will accommodate a wide variety of pipe sizes. Jaw blocks are removably attached to the mandrel attaching block to increase or decrease the clamping size of the mandrel. A mandrel mounting head is readily removable from a mandrel shaft so as to provide further variation in clamping size or function. All of the clamp actuating mechanism, as well as the tool feed mechanism is contained within the interior of the mandrel shaft to prevent contamination from external sources, but is readily accessible from the exterior of the mandrel shaft. Laterally spaced apart bearing surfaces between the mandrel attaching blocks and the mandrel mounting head, as well as a torque ring insert interposed between the mandrel shaft and a mandrel adapter provide for the torque reaction between the cutting tool and the mandrel so as to provide a rigid, sturdy base for the cutting tool.
