Claim:
1. A tool for scarfing a rotor blade segment, the rotor blade segment comprising a pressure side, a suction side, a leading edge, and a trailing edge each extending between a first end and a second end, the tool comprising: a first guide configured for mounting on one of the pressure side or the suction side of the rotor blade adjacent to a cutaway portion thereof, the first guide comprising a first curved rail mounted to a single first mounting component secured between the ends of the first curved rail and a second curved rail spaced from the first curved rail, the first mounting component being secured within the cutaway portion of the rotor blade, the first curved rail and the second curved rail each being rigid and having a curvature that generally corresponds to a curvature of the one of the pressure side or the suction side, the second curved rail being offset from the first curved rail such that a distance between the first and second curved rails and a difference between top surfaces of the first and second curved rails defines a scarf angle; a second guide movably coupled to the first guide at the scarf angle of between approximately 1 degree and approximately 5 degrees, the second guide comprising a pair of parallel guide rails spaced apart along a chord-wise axis of the rotor blade segment, the pair of parallel guide rails extending between and movable along the first curved rail and the second curved rail; and a cutting device movably coupled to the second guide, the cutting device slidable between the pair of parallel guide rails during operation of the cutting device and operable during movement along the guide rail to remove material from the one of the pressure side or the suction side.
