when you make the studs that go in AL3 the part that is in the casting is usually a course thread and the part for the steel nut is usually a fine thread ? When you lap in the valves you usually just lap about a 1/5th of the valve , not the whole valve..??!! this is what i do with my Morris Minor !!!
Mike asked what the next engine will be. Well, it is this one, a Peerless TC4 lorry engine of 1915 vintage which, as you can see is installed in a lorry. We have started stripping it down and generally, it is quite nice apart from a couple of horrors. Nothing like a challenge!
If I make another model engine, it will be a Liberty, assuming I live long enough. Has anyone ever made one?
