Well, took a month longer than anticipated, but I'm now back at it! Starting what will be a lot of operations on the cylinder block casting, a quick run over in the mill to create one flat face to build from for all the various ops: That done, into the lathe to bore the hole for the cylinder liner: Using the bore to locate the casting, machined the valve face almost to finished dimension, leaving a little meat for last minute adjustments That gave me a reference face for the vise so I could cut the curved surface that sits on the barrel of the boiler. I used a freshly sharpened HSS tool in a fly cutter, this casting machines like a dream! Had an off-cut of the boiler material to use to check for fit... Lots more to go on this bit. |

Joe, was that a casting to start with, or did you fabricate the curved saddle onto the cylinder, or cut it out from solid? Looking great! :beer: |

Brill work :drool: |

Thanks Kev. Steve: A casting, and a very nice to machine casting indeed. Something in the bronze family, and heaps of machining allowance all around. Joe PS Steve, Don't forget to come up to Windsor next week-end! |
