Processes, systems, and apparatuses are disclosed for forming products from atomized metals and alloys. As a result, highly-accurate, highly-stable alignment of an optical axis can be readily realized. The first end plate is coupled to a first end of a back axle shaft shroud, where the back axle shaft shroud includes a first shelf hook and a second shelf hook. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.
