Check-It-Gauge - Special Uses

Special Applications
To check the second upper shutoff angle a combination of two roll pins can be used. The roll diameters can be added to a CAD drawing to obtain the step height.
Another application for checking the depth of a shutoff that has two angles is to use a roll pin and Check-It-Gauge.
This is an example of a 5 degree shutoff being inspected by using a roll pin and Check-It-Gauge.
If the reach from the plate edge to the point of measurement is too great, gauge blocks can be added. To achieve a higher degree of accuracy, calculate the exact combination of gauge blocks and a roll pin to extend to the edge of the plate. Then a comparative measurement can be taken to verify a zero distance.	(Click images to enlarge)

Comparative Measurements
Zeroing out the Check-It-Gauge to a preset group of gauge blocks is an accurate way of doing comparative measurements.
Showing the reverse of the above, the gauge blocks are placed under the base of the Check-It-Gauge. This allows for you to make accurate comparative measurements below the reference plane* surface.	(Click images to enlarge)
