8 Great ways to use a combination square
3. Accurately set heights for blades and bits
The photo on the first slide shows a method we like for setting tablesaw-blade and router-bit heights: Lock the head on the rule at the desired height, and then raise the cutter until it just kisses the head. Be sure to hold the rule end on the table surface rather than the throat insert. Adjust the blade or bit up or down as needed. Or, place the combo square's head on the table and slide the rule up against the cutter, as shown left.
