Orientation Gauge

The Otto Frei Jewelers Orientation Gauge has been developed by famed goldsmith Doug Zaruba in conjunction with Otto Frei. This 2-1/2" x 3-1/4" gauge can help the metalsmith with layouts and for checking symmetry. Use it to find the center of a circle or for making precise angles, or like a machinist square for checking the accuracy of your work. Made of clear acrylic with an etched grid of 2.5 mm squares. Mounted on small rubber feet that grip on smooth surfaces. Made in the USA.
