Why ductile cast iron is not an acceptable alternative for cylinder liner/ piston rings? I know the the grey iron has favourable tribological properties but steel is also used for liners/rings. From my experience ductile iron is in the middle concerning machinability and wear behaviour. It also...

Hi, I am looking for plans/ideea for my first builds. My targets for the moment are rather utilitary engines -though I'm not intending yet to use them in any project. They should be small capacity 4 stroke singles - side valves/ OHV and OHC, also have in mind a boxer twin of same type and maybe...
