Thanks for the tip on the gloves. Another thought has occurred to me, with the grinding wheel or the sawsall but probably better with the grinder, you could use a length of cable, something like that aircraft cable, heavy cord would probably also do but you make a tight loop at the pivot point and another around an appropriate point on the cutting tool of choice and just keep it really tight as you go around.
The disk cutter actually now sounds like a better choice because it won't bind or work the metal possibly damaging it or the paint finish. Should be a smoother action. wouldn't work though with the stick or rod.
