Tool Review: Robert Larson 800-2875 Center Finder
If you’ve ever struggled to locate the center of a circular plate or a piece of round stock using a ruler or a square, you know it can be a tricky proposition. My usual ham-fisted method involves marking the midpoint of several diameters and kind of visually averaging all those sloppy centers to get roughly in the middle of the thing. If I need more accuracy, I try to sandwich the circle between two framing squares and then draw lines between opposing corners–lines which, at least in theory, should bisect each corner at 45 degrees and intersect in the middle of the circumscribed circle. In theory.
