casting a body comprising:
a first body end and a second body end disposed opposite from the first body end, wherein the body defines an axis extending from the first body end to the second body end, wherein the body comprises a first neck disposed proximate to the first body end wherein the body further comprises an inner body surface defining a bore extending through the body from the first body end to the second body end, and wherein the body further comprises an outer body surface spaced from the inner body surface a predetermined wall thickness,
wherein at a first location on the axis, the inner body surface is unmachined and defines a first distance from the axis, and at a second location on the axis that is spaced from the first location, the inner body surface is unmachined and defines a second distance from the axis that is greater than the first distance, and wherein at the first location, the outer body surface is unmachined and defines a third distance from the axis and at the second location, the outer body surface is unmachined and defines a fourth distance from the axis that is less than the third distance; and
machining the inner body surface at a portion of the first neck to define a seal cavity in the first neck and machining a portion of the outer body surface of the first neck to form a jaw engagement surface on the first neck, wherein the portion of the first neck defines the second location and wherein the first location is spaced apart from the portion of the first neck.
