Toughy but a goodie, I did this quick while at lunch so you'll need to touch it up.
Create a cylinder that encompasses the body (I used an extrude) TURN OF THE MERGE RESULTS (Very important) Now you have two bodys occupying the same space. Draw the profile you want to cut out, on a tangential plane to this cylinder and wrap it into the cylinder to the depth you want (note, the cut will have and ultimate depth not a relative to surface, I hope this works). Then use the intersect tool to select the final bodies you want to keep.

Attached are snapshots of the process and the cut model. It will need to be cleaned/ I suggest you redo it. if nothing else this is a super good practice model.
Very Nice.
