Center Finder for Large Round Objects

This small center finder is designed to be used in conjunction with a standard wooden yard stick to find the center of a round object with radius of up to one yard. Metal yard sticks can also be used if they have a width of 1 1/8" or less, though the fit may be loose. This isn't designed for and I haven't tried it with meter sticks or other rulers. When selecting a yard stick to use, be sure to pick one which is very straight or your center will be off.
