AW Extra 4/26/12 – Circle Center
By George Vondriska
Quickly find and approximate the center of a narrow board by using your fingers like a marking gauge. Set a pencil in your fingers, allowing one finger to run along the face of the board. Make a line parallel to one face, turn the board over, and make a line parallel to the other face. The center is halfway between these two lines.
