Progress so far: Cylinder liners are fitted to place. Cylinder bodies lower parts are to be squared. Two brass pieces on the front are for heads. Not yet sure, are they thick enough. |

Ahh, starting to look like an engine now! :thumbup: |

It looks like you're making some good progress on the engine. Could I ask how you're going to operate the valves? I know with a camshaft but where are the cam followers going to go? George |
| NickG:
OHC? |

Small addition: On previous pic there was some extra material on the cylinder bodies, to make the jig drilling easier. It's now machined off, allowing liners to go to bottom. One thing I discovered about SS 2172, that the SS doesn't stand for stainless steel, but for 'Swedish standard'. Anyways it is a low carbon steel, that can be hardened. Sort of tool steel I guess. Stainless would have been better for liners, as the iron piston doesn't get so easily stuck with it. When using ethanol as a fuel, ferrous metals tend to gather rust. |
