Special lathe developed at Snyder Corp, Detroit, Mich, for machining railroad car axles uses new tracer system concept with no hydraulic, electrical, or lubricating connections to carriage or feed assembly; identical cast iron head and tail stocks powered by individual, 150- hp d-c motors operating as one 300-hp system, support hydraulically-operated compensating chucks; lathe-tracer turns barrel part of axle with pair of opposing tool blocks; tracer template is carried in holder supported in horizontal plane by spring-loaded parallelogram linkage that prevents it from traveling in any direction except at right angles to axle centerline.
