I use an old toaster oven to cook out the hard wax that many of these caps have in the ends, about 200 degrees or so usually works, but in some instances they used some sort of putty or plastic that refuses to melt, some of the "Good All" brand caps use this ( one guy on Y.T. refers to them as Bad All), I have not encountered this stuff in any Aerovox caps as yet. The ones with the porcelain shells are almost a waste of time, maybe one could get them apart with a drill but the ends are filled with cement of some kind.
