After studying metrology and machining techniques, I manufactured a Tesla turbine, holding tolerances of one thousandth on the two-axis CNC mill and the manual lathe.
The final turbine spun at 35,199 RPM when tested with 100 psi of air. This beat the previous speed record for the other turbines that had been manufactured during the Fundamentals of Machine Shop Operations class. It spun so fast that it began to destroy it's bearings and, according to calculations, experienced inelastic deformation.
