Austin Jones at J.H. Benedict has been very nice to send us several pictures of our 4340 steel exhaust pistons throughout the manufacturing process. They are almost finished. There is still some grinding to do and some machining on the crown. You can see they did the turning operations first on the lathe, and then machined out the inside of the piston. Bushings for the wrist pin will be machined and ground out of a bronze alloy and pressed in later.
