Claim 0:
1. A portable lathe assembly kit for operatively installing a portable lathe on a cylindrical workpiece having a longitudinal axis, the portable lathe assembly kit comprising:
two frame members configured to operatively support the portable lathe on the cylindrical workpiece when the portable lathe is operatively installed on the cylindrical workpiece;
a plurality of guide bars configured to extend between and operatively couple the frame members to one another;
a tool assembly configured to be supported by the plurality of guide bars between the frame members and including a non-rotating portion and a rotating portion configured to rotate relative to the non-rotating portion about a rotation axis; wherein the tool assembly is configured to translate along the plurality of guide bars and along a direction at least substantially parallel to the rotation axis when the portable lathe is assembled and operatively supported on the cylindrical workpiece; and
a feed assembly configured to be operatively coupled to the tool assembly and configured to translate the tool assembly along the plurality of guide bars when the portable lathe is assembled and operatively supported on the cylindrical workpiece;
wherein the feed assembly comprises:
a first fixed linear feed element configured to extend between the frame members;
a driving rotary feed element operatively coupled to the tool assembly and configured to operatively engage the first fixed linear feed element;
a second fixed linear feed element configured to extend between the frame members and at least substantially parallel to the first fixed linear feed element; and
a driven rotary feed element configured to operatively engage the second fixed linear feed element; and

wherein the feed assembly is configured such that rotation of the driving rotary feed element relative to the first fixed linear feed element causes the driving rotary feed element to translate along the first fixed linear feed element and rotation of the driven rotary feed element relative to the second fixed linear feed element causes the driven rotary feed element to translate along the second fixed linear feed element, thereby urging the tool assembly to translate along the plurality of guide bars.
