1. A woodworking machine having a cutting region for cutting work pieces, comprising:
- a motor;
a movable cutting tool powered by the motor and adapted to cut work pieces in the cutting region;
a detection system adapted to detect one or more dangerous conditions between a person and the cutting tool; and
a reaction system associated with the detection system and the cutting tool, where the reaction system is configured to retract the cutting tool at least partially away from the cutting region upon detection of at least one of the dangerous conditions by the detection system, where the reaction system includes an arbor block, and where the motor is mounted to the arbor block.
