Abstract
A carpenter's gauge for use as a marking gauge or a compass includes a compass bar, a pin carrier, and a marking instrument holder. The compass bar is an elongated bar having a slot formed along its center. The pin carrier slides along the compass bar and includes a pin holder and a knob located opposite the pin holder along the compass bar. The pin holder includes a reference surface that lies substantially in line with a pin held by the pin holder. The knob allows the pin holder to be rotated between a first position where the reference surface lies parallel to the compass bar, and a second position where the reference surface lies perpendicular to the compass bar. When the reference surface lies perpendicular to the compass bar, the gauge may be used as a marking gauge or a compass by inserting a marking instrument into the marking instrument holder. Etched markings along the compass bar indicate the distance between the reference surface or pin and the marking instrument. When the reference surface lies parallel to the compass bar, a nest in the marking instrument holder protects the tip of the pin.
