I needed to turn this shape for a current engine build, where I had Solidworks model for the part.  Converted to DXF, adjust the outline, and created a pointlist along the curves with 50 thou spacing.  I was able to display the points and screen print them.  Then used a cutoff tool with DRO assistance.

Preliminary sanding with 80 grit got most of the steps out.

In brass you could also set up a rest and hand turn it to smooth it out.  A round insert carbide wood turning tool works nicely for this sort of thing.  Not my idea.  I saw a video of a guy hand turning contoured new handles for his metal lathe that way on YouTube using his metal lathe and a rest.  He did still file and sand to final finish. 

Good job roughing it out.  Its going to look nice when you get it finished. 

Getting started on CNC?  In or passing through my area?
If I have the time I'll be glad to show you a little in my shop.
