I think you could do the whole thing out of a solid piece on the S3. It would take a while.

The groove/ring could be done with a T-slot mill or something similar. What you want is this: http://mindworks.shoutwiki.com/wiki/Fil ... d_Mill.jpg

If all you need on the back side is a chamfer I would probably do that by hand or on a router table with a bearing guided chamfer bit. Indexing the part adds unneeded complexity.

Heres an example of router bits that have a similar profile to what you need.

Its a groove for a carb boot seal. I'm thinking this piece would be better suited for a lathe.
I dont think you would have a problem cutting that on a 2.5D machine with the convex radius cutter in my second link..especially if you dont need tight tolerances.

If thats meant to be all 1 piece...im not sure you could ever lathe it.

EDIT: nevermind...i just read where you mentioned it will be multiple components.

I really could forego the chamfer and save myself the headache. The spigots will be a challenge since they have an internal parabolic reduction.

As long as the taper is wider on the top than the bottom you should be able to cut it with a long ball end mill.

Programming the g-code might be a bit of work depending on what CAM software you have access to.
