Now we're going to work on the details of the body. These will be simple pockets and contours on the face of the owl. We're going to start out by making the wings look partially separated from the body. Just make another arc inside off of the wing so there is a gap between the body and the wing. Offset the arc into the wing so that you have two arcs with a .125" space between them because the smallest tool that will be used on the mill will be a .1" tool. There should always be a tolerance from the tool and the material. Extrude the gap between the spaces so that it cuts into the material .25"
