Mirror the part so you have a large round hole in the middle. Make up your stock sized for two parts with a half inch cut area down the centerline. Now finish the elongated round thru pocket in the center. Put a flat piece of Alu. in the vice and cut a male version of the elongated round pocket, add a few tapped holes for clamping down the part. then put TWO parts at a time on your little fixture and cut All the outside stuff. Saw them in half and finish the last faces and put in your tapped holes. Two Bangs for one buck!!! The flats on the inside profile will clock the parts for you. Good luck
