Sam,

Try HEAT. I have an OXY/MAPP setup that may work if the bolts have some bite left. Shoot me a PM. I may be avail this evening.

Steve,

I know the cut off discs you are talking about and they stink. The 'good' discs are fibre reinforced and rarely break unless you really tweak them. They are also a bit more expensive ~$1/piece.
