ABSTRACT:
The tool kit comprises a set of angle gauges for measuring angles in a workpiece being formed in a sheet metal bender, and printed math tips and charts related to the angle gauges. Each angle gauge has an elongated shape with juxtaposed longitudinal base surface and longitudinal angled surface, and an indicia thereon indicating a nominal angle. The angled surface makes a true angle with a transverse projection of the base surface. This true angle corresponds to the sum of the nominal angle on the indicia plus a supplement angle. The nominal angles on the angle gauges in the set are different from each other, and the supplement angle is common to all angle gauges in the set. The supplement angle corresponds to the slope of the nose bar in the sheet metal bender. The entire set can be used on a same bender to measure different angles.
