A grapple mechanism is connected to a post driver on one side, rather than in the front of the post driver. The abrasive particles comprise diamond particles, and the treating is performed in the absence of an effective amount of crystallization agent on the contact surface. The system also includes a processor to co-ordinate actions of components to process data pertaining to evaluation of the measurement of the flow of air, and translate the measurement of the flow of air to clinically relevant parameters.
