The carriage carries the crossfeed slide and the compound rest which in turn carries the cutting tool in the tool post. The carriage slides on the ways along the bed the wings of the H-shaped saddle contain the bearing surfaces which are fitted to the V- ways of the bed. The cross piece is machined to form a dovetail for the crossfeed slide. The crossfeed slide is closely fitted to the dovetail and has a tapered gab which fits between the carriage dovetail and the matching dovetail of the crossfeed slide. The micrometer dial on the crossfeed handle is graduated to permit accurate feed. Depending on the manufacturer of the lathe, the dial may be graduated so that each division represents a 1 to 1 ratio. The compound rest is mounted on top of the crossfeed slide
