Thank you Kim
That's just red marked pen to keep the orientation until I make some permanent marks.
Due to my small machines I could not make a long enough crankshaft so now I need to add an extension to drive the water pump etc. As the crankshaft was in the lathe I turned a small radius on the webs to make it easier to fit into the crankcase. The extension will be in two parts, a sleeve and a sacrificial extension shaft. I chewed up the end of the crankshaft on my diesel trying to start it and expect similar problems with this engine so I shall make it replaceable. The starting dog is not keyed to the shaft, just clamped, to act as a mechanical fuse.
The end of the crankshaft was turned down to 8mm and a 12mm sleeve was drilled and reamed to fit. The sleeve was then broached for a 2mm key. It will be Loctited to the end of the crankshaft and the extension will use the same key but be held in place with a couple of grubscrews.
