501 forum posts 132 photos | Hello all, I making a 2/3scale AA RAYMAN marine steam engine and now on the cylinder. I've made the cylinder out of what I think is bronze, it's 50mm wide with a 12mm hole through the large lump that I've got and looks like a casting but with a bronze colour. What material would be best for the valve that will side on the cylinder face. Another question I have a large bar of 55mm bronze which is copper coloured which is different from other bronzes it's tough and difficult to drill that it will grab,any idea what this could be, it has the wave heat lines on the bar so know it's some type of bronze. As with the engine it will not get much use, it's just making it and fitting it in a boat,minimal use. Thanks Bob
