Disclosed is a portable machining lathe for machining a pipe or similar workpiece. The lathe includes two semicircular members having a stationary section and a rotatable section. The two semicircular members are cooperatively connected by a hinge system on one end, and steel splice plates on the other. The hinge has a top bracket and bottom bracket on the stationary section of each member, and a male hinge and female hinge on the rotatable section of each member. The male and female hinges are cooperatively connected so that when the hinge is closed the two semicircular members form a complete annulus.
