Although not by a known machine-tool manufacturer and believed to be home made, the "JR Micro-125" lathe is marked on its headstock speed plate, "DEEP RIVER, ONT". Deep River, in Ontario, Canada, is small town close to the Atomic Energy of Canada Ltd. plant at Chalk River.
Twenty inches long, the lathe is both backgeared and with power feed to the carriage - though the arrangement of the coarse-pitch leadscrew look to preclude screwcutting. With a swing of x" and taking y" between centres the lathe has a dog clutch to engage the carriage drive and is fitted with a proper compound slide-rest assembly, the top slide able to rotate through 360°.
