By means of a sine bar and with gauge blocks, a reference plane can be created at an angle 0° to 60° with respect to the base. The base of the sine bar consists of two rollers with a center to center distance of 127 ± 0.004 mm. In order to make a curve the gauge blocks are placed under one of the rollers
