The Gauge-It lets you easily and accurately measure blade height and angle on your table saw. It compensates for blade teeth to give you accurate measurements, and the spring-loaded armature moves with your blade, indicating the exact angle.
When measuring blade angle, place the Gauge-It perpendicular to the blade with the armature resting on the body of the blade, not the teeth. As you tilt the blade, a spring keeps the Gauge-It in contact with the blade, indicating its angle to within 0.5˚.
When measuring blade height you disengage the spring, align the Gauge-It parallel to the blade, and rest the curved lip on your saw blade — it rides the blade while you adjust it up or down and indicates the height to within 1/64″.
Also, with the scale on the base of the Gauge-It, you can measure the distance from the blade to the fence. It’s marked from 0 to 6-1/2″ in increments of 1/32″.
The Gauge-It comes in both left- and right-tilt versions. Either version costs about $30.
