I am building the Clayton Wagon and have come to the crossheads.
I only have one gun metal casting, don't ask I don't know what happened to the other one. Would it be a problem if I made the other one from brass or should they both be the same material and if so why apart from looks?
Thanks in advance

Simon, crossheads are made from gun metal so they wear well, brass will not wear anywhere near as well, could you get a lump of bronze or gunmetal and use that?

Gunmetal is a variety of bronze and formerly used for making ordnance (guns).
Modern admiralty gunmetal is composed of 88 percent copper, 10 percent tin, and 2 percen zinc and is used for gears and bearings that are to be subjected to heavy loads and low speeds. It withstands atmospheric, steam, and seawater corrosion and is suitable for valves, pump parts, and steam fittings.
