messed up weekend!

Hope it lasts a while to geter done.I gotta ask you though and yes I have read the old threads.What have you found to cut the one copper windings end from the armature?I have cut several ends off with various types of sawzall blades,bandsaw blades and even used a grinder with a cutoff wheel.Do not care for the cutoff wheel cause of the copper dust floating in the air.(breathing it)I know I can use a mask and so on,but was wondering what you have found that works best.
