Geometric Center

by Lynn Pratt

Updated Nov19, 2003

To find the geometric center of anything, cut a 14" circle (7" radius) out of clear plexiglas with a small hole at the center.  Scribe concentric circles at 1 inch intervals. Place the device on a piece of wood, look through it while centering the circle that is closest to the outside diameter of the blank. This will give you a center  point for a faceplate etc. as well as giving you an idea of what diameter the final turning will be.
