Cast iron billet
Lead machinist Sam Thompson is currently machining three pieces for the valve set up from a heavy cast iron billet. They are for the steam engines on the Diamond and Caldor No. 4 Shay locomotive. After completing the first part, Sam used the electric shop forklift to move the billet from the lathe to the power hack saw in the next room. From there he cut off the part and returned the billet to the lathe to machine part number two.
