Vaucanson’s metal cutting lathe at the musée des arts et métiers in Paris. The view is looking down the prismatic ways, with a lead screw viable between them. The ways and lead screw are made of an iron alloy. At each end a brass mount supports the ways and lead screw. In the middle a brass carriage sits on the ways with a cross slide mounted on top. A tool with interchangeable cutter is mounted on the cross slide. To the left is the centre to which the workpiece is mounted. A frame of black wrought iron alloy surrounds the lathe. The lathe itself is on a glazed wooden display case.
