Here are the 1/2 shaft parts getting ready to be hardened. Notice we are polishing to a mirror finish the 1/2 shaft axles. We don't want any stress raisers in those babies! The parts on the bottom are the hub end of the 1/2 shaft. The parts on the top are the differential end of the 1/2 shafts. We made a few extra parts as you can see here.
