complex shape in solid works

[asv4k8]

I am having trouble creating the shape cut out i want. I have basically a semi circle cutout of a solid part but on the curved edge of that part i need a lip to divide the two halves. I tried creating it with 3 separate sketches/cuts but I cant get them to align properly. I had to use 3 separate cuts because there is the divider "shelf or lip" that fits in the groove in the cam. (see pictures)

Create Reference Planes (before the cuts) and use those for alignment.
