The advancement projection includes a contact-surface. The advancement member is coupled to the tool support. Upon the advancement member contacting the contact-surface of the advancement projection the advancement member is adapted to advance the tool towards the pipe at the increment. The contact-surface of the advancement projection is shaped to always be in a non-perpendicular contact position with the advancement member.

Portable lathes, portable lathe assembly kits, and associated methods. A portable lathe comprises two frame members, a plurality of guide bars, a tool assembly supported by the guide bars, and a feed assembly for translating the tool assembly along the guide bars. The feed assembly includes a first fixed linear feed element, a second fixed linear feed element, a driving rotary feed element, and a driven rotary feed element, and is configured such that rotating the driving rotary feed element translates the tool assembly along the guide bars. A portable lathe assembly kit comprises components of the portable lathe configured to be assembled together to install the portable lathe on a cylindrical workpiece. In some examples, a method of utilizing the portable lathe assembly kit comprises operatively receiving the cylindrical workpiece within the frame members by securing the cylindrical workpiece to a first lathe clamshell subassembly and operatively coupling a second lathe clamshell subassembly to the first lathe clamshell subassembly.

Pipe machining apparatuses and bearing assemblies are provided. In one aspect, a pipe machining apparatus includes a frame, a tool carrier, a first roller bearing and a second roller bearing. The tool carrier is coupled to and movable relative to the frame and defines a race therein. The first roller bearing includes a first shaft and a first roller rotatably coupled to the first shaft. The first roller is at least partially positioned in the race and is rotatable about a first roller bearing axis adapted to remain substantially fixed relative to the frame. The second roller bearing includes a second shaft and a second roller rotatably coupled to the second shaft. The second roller is at least partially positioned in the race and is rotatable about a second roller bearing axis. The second roller bearing is adjustable to move the second roller bearing axis relative to the frame.

Pipe machining apparatuses, coupling members, and methods of assembling pipe machining apparatuses are provided. In one aspect, a coupling member for coupling together a first section and a second section of a pipe machining apparatus includes a first housing member adapted to couple to the first section, a second housing member adapted to couple to the second section, an arm movably coupled to the first housing member, and an engagement member coupled to the arm. The arm is adapted to move between a coupled condition, in which the engagement member engages the second housing member, and an uncoupled condition, in which the engagement member does not engage the second housing member.

According to an aspect of the present disclosure, a low profile travelling pipe cutter is provided which is adapted to perform at least one of cutting and beveling a hollow vessel while traveling around the vessel using a cutting tool mounted thereon. The pipe cutter includes inner and outer carriages, a capstan assembly attached to the outer carriage to which a feed cable is attached, and rollers attached to the outer carriage to which a tension cable is attached. The force adjustment assembly changes the vertical position of the outer carriage relative to the inner carriage to compensate for the pipe cutter going inwardly and outwardly as it travels around a hollow vessel in order to maintain constant pressure caused by the lever tension interface. A guard assembly is provided for covering and uncovering the cutting tool during cutting.
