Sine Bar Gauge Block Stack Calculator

How to use it: enter the certified roller-centre distance and target angle. The tool calculates height, then searches a representative metric gauge-block set for a short stack near that height.

Formula. Stack height = sine bar length x sin(angle). The combination search works in one-micron increments and reports residual height and achieved angle.

Example. A 100 mm sine bar at 30 degrees needs a nominal 50.000 mm stack.

The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.

Primary result: Target height: 50.0000 mm.

• Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
• Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
• When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

This is a nominal planning aid, not a calibration certificate. Verify available block sizes, individual calibration corrections, wringing condition, temperature, cleanliness, bar calibration and setup direction. Never force an unstable stack.
