Sorry, I meant the hollow face that sits against the outside of the cylinder, where it got soldered together. I am not sure the best way to mill that curved surface on the top of my base piece to mate against the bottom of my crosshead tube.
Here you go Chris!
Great fits on those rods Chris, well done. Going back to the pondering of the trunk guides for a second, I missed the fact that the cylinder flange was flush with the base front face. (I was probably overcome by rum fumes over the phone ) The flange OD would not be machineable with a flycutter type tool on the between centres boring bar I had in mind, as you mentioned. (unless you made a non-protoype relief slot below the flange on the base front face). Anyway, got the ready for when you tackle the trunk guides. At the great rate you are working, it won't be long.Regarding the "infinite radius arc" discussion about the expansion link - are you sure the slot faces aren't actually two 450,000-faced polygons?(I'll get me coat and hat now - hmm, time for some egg nog maybe........ )
That setup should help when I get to the Stanley engine project, it has two cylinders connected by a bridge piece like this base, this will let me shape that block too. Which will make Zee happy as well...
Sending the idea to Zee's shop gnomes might be OK, anonymously of course.
