The rig is constructed with similar geometry to a conventional lathe, comprising a “head-stock”, for carrying shaft samples, a “tail-stock”, mounting a combined axial force and radial torque transducer, and a “tool-post”, for mounting a specimen and applying a radial force.
The head-stock and tail-stock assemblies are mounted on standard linear slide, on bearing blocks, with manual clamps.
