Thanks all for the advice. I give it a try, with safety glasses, as per Zach's advice, and needle nose vise grips and see how it progresses. I,ll bring the gun to Hausmann's in any event and have the expert, who I suspect, is Dave Williamson, go over the process with me, if he is so inclined.
thanks again. It never falis to amaze me how much expereince is on this web site.
