Make Stronger Doors with your Tablesaw
In the stile, center a 1⁄4 "-deep groove for the panel with your dado blade. Then, raise the tablesaw cutting depth up to 1". Measure the width of your tenon and clamp a stopblock to your tablesaw fence as shown at far right. Then, run the stile groove-side down over the dado blade to the stopblock.
