I made a bench out of old barn board.
You basically need five pieces. I didn't have wide enough wood so I glued together two 6' pieces side-by-side which gave me about an 11 1/2" width and then I cut that into three pieces for the top and legs.
The height of the legs is 18", so I cut two and then cut out the V shape.
The top piece is about 3' long.
The side pieces are scraps of 3 1/2" wide boards that I put a 45 degree cut on each end as you can see from the photo.
Everything was nailed together, and then the cut edges were covered with my not-so-secret recipe which I will share in a day or two when I organize the photos.
This is an old looking, very solid bench that is easy to make and similar to my bench I posted here, except it has the two side pieces instead of a middle piece.
