The finished basement stairs for this project will be built with prefinished maple treads from lumber liquidators and 1×12 clear pine stringers and 1×8 clear pine risers. The stringers and risers will have a clear sanding sealer applied under four coats of water-based urethane wood finish.
The picture above shows the stringers marked for 9″ treads and 8″ risers using a framing square and square points.
The bottom layout must be adjusted by the thickness of the treads. Since we are using 1″ maple treads 1″ must be cut off the mark of the bottom rise.
Cleats can be attached to the riser and tread marks to support the risers and treads. 2″ pine cleats can be glued and screwed as in the following picture.
7″ high Risers can be ripped from the 1×8 pine and the stringers and risers can be sealed and urethaned.
