Here’s a cool trick for cutting a bunch of identical notches without a dado stack. Carefully cut an accurate notch from the end of a board, exactly the same dimension as your desired notch. Attach a clamp board to the other end of the notched board and clamp the assembly to your saw’s fence. Mark the notch location on your workpiece and set the fence. The jig’s end registers the first cut. Slip the workpiece into the notch for the second cut, and then make multiple passes to clear the remaining waste. – Craig Harper.
