Applying the Socket
1) hold socket firmly in hand with the socket hole squarely in the center of your palm
2) anchor the wrist, all the way to the knuckle, firmly against the shinbone. Do not allow any separation to occur, otherwise you will lose stability
3) check the drill, it should be straight up-and-down. If it is leaning,either forward or back, adjust your body by shifting the angle of your left leg, and/or move your foot on the fire-board either forward or back.
Next: spinning the drill
