You may build a fence to provide a secure boundary around your property or improve the view from your yard. When building a fence, the cost and durability of the material are considerations. Although there are many different materials and styles from which to choose, most fences include fence posts. Fence post caps add beauty and style to the top of plain fence posts. Although fence post caps are available in various materials and designs, you can make your own basic caps with a few simple materials.
Cut the 2-inch-by-8-inch lumber into 8-inch-long pieces. This creates squares for the fence post caps. Cut as many squares as you have fence posts.
Tilt the table saw blade to 15 degrees. Adjust the angle if a steeper or shallower point on the cap is desired.
Clamp a tall board to the table saw fence. Stand a post cap square on its 2-inch side on the table saw top. Clamp a piece of scrap wood to the post cap square.
Slide the post cap square on the saw to cut the bevelled edge. Repeat for all four sides of the post cap.
Repeat the bevelling process for the remaining post cap squares.
Smooth the surfaces of the post caps with the 120-grit sandpaper.
Stain or paint the caps as desired. Allow the stain or paint to dry thoroughly.
Glue a cap to the top of each fence post with wood adhesive.
Cedar is a durable choice for fence post caps; unlike most other woods, cedar doesn't need to be treated.
Call your local government to ask about local codes governing fences and to make sure there aren't any required permits for fence work.
