They are castings of my design. They are aluminum castings with brass sleeves. I find that when I have the engine running on steam the aluminum cools the steam off quite fast. Makes for not as efficient engine. The cylinders should be cast iron but I am not set up to to pour cast iron.
is that a set of Reliable castings?
