Begin by installing the riser boards. Cut each riser board to length and attach it vertically between the stringers, flush with the front of the step cutouts. Use construction adhesive on the stringer contact points and secure with screws. Once all risers are in place, install the tread boards. Again, apply construction adhesive to the top of the step cutouts and any intermediate supports. Use a scrap piece of wood as a spacer to ensure a consistent 1/4 inch overhang for each tread. Secure each tread board with screws (three screws per stringer was suggested for optimal security).
