That works but it pretty much destroys the evacuation port for future use. I have the same intentions and have collected several B/W guns. My technique is to use a dental turbine (a dremel will do) and bore an about half mm hole through the neck downstream of where I plan on cutting it. That way I can re-open the tubulation in a controlled manner and reuse it.
