Got it up on the mill and put the bolt circle in.
First time I have aligned using the conical center finder, and it really works well, just using your fingers to feel the alignment. A quick check with a micrometer in two directions verifies location. You all know this of course.
The bolt hole pattern aligns very well indeed with the one I put in the outboard cylinder head, which pleased me to no end. Good test of repeatability of the rotary table and mill set up.
Then machined the snout to size. Parting off was a gentle and slowly slowly approach.
Then cleaned up and brought to size with a knife tool.
Turned the part around, and brought the part to final thickness.
Pretty happy with the final finish on that.
One last step to do, which is machine a step on that face. Hopefully get to that tomorrow.
Much better progress today. I’m sorry my posts aren’t a bit more interesting, but I'm working at the very basic end of the spectrum of model engineering, in terms of knowledge, experience and skill, but I'm having a good time, and even having some success - if not very consistent success, so I think that counts for something. Still going to make this engine run. Although that day seems a long way off yet.
