Set the cutting depth of tablesaw blades easily using this adjustable gauge. To ensure accuracy, we outfitted it with a steel rule. See the Buying Guide below for our source.

Start by cutting the body to size from 34 " maple, as shown in the drawing. Plow a 1332 "-deep groove, sized to fit your rule, in one face of the body, where shown.

Next, set your dado blade to 14 ", and cut the combined rabbet and groove in the body for the sliding bar. To do this, place the gauge body on edge, with the ungrooved face against the fence. Cut the rabbet/groove in three passes, with the last one at 1-34 ".

Drill and countersink the screw hole. Then sand and finish the body.

Use a coping saw or scrollsaw to shape the 14 " acrylic sliding bar to the dimensions shown. Create the adjustment slot by drilling a pair of 516 " holes, and cutting out the material between them. Smooth the edges of the slot and the outer edges of the bar using a fine file. Buff the outer edges if you want to make them supersmooth. Now, scribe a cursor line on the back face.

Fit the steel rule into the groove and attach using double-faced tape. Place the bottom end of the rule 14 " from the bottom of the body. Then install the sliding bar.

To use the gauge, set the cursor line to the desired height. Hold the sliding bar in its groove while adjusting the gauge to keep the bar square with the base. Place the body on the tablesaw top beside the blade, as shown in the photo, and raise the blade to set the height.
