5% Nickel-Copper Alloy
I made this quadrant in part to document the step-by-step process of traditional graduation with hand-tools. A variety of traditional 19th and 20th century tools are also displayed, including compass dividers, beam compass (trammel points) with fine setting screw, punches, scribe, straight edge, rule and figure punch set.
