I would be tempted to try the 'old spot annealing carbon stick/torch'.
For years I have read/watched the suggestion of using a V-block to support the receiver and a drill press with a screw driver bit. And that always causes me to believe the world is unfair. I do not have a Mauser screw that will tolerate the torque.
