- Apply wood glue to the overlapping areas.
- Secure the rails together with 3-inch decking screws, 2-inches apart.
Cutting Rails
Rails need to be cut to the correct length and angle for the specific staircase design.
- Measure and mark the desired length on the rail.
- Use a miter saw or circular saw to cut the rail at a 45-degree angle.
- Make sure the cut is clean and free of splinters.
Installing Spliced Rails
Once the rails have been spliced, they need to be installed on the staircase.
- Position the rails on the staircase, ensuring they are level and plumb.
- Secure the rails to the stringers using 3-inch decking screws, 16-inches apart.
- Check the stability and alignment of the rails before tightening the screws.
Installing Balusters
Balusters are the vertical members that run between the top and bottom rails of a deck railing. They provide both support and style to the railing. Balusters can be made from a variety of materials, including wood, metal, and PVC. The most common type of baluster is the round wood baluster. Round wood balusters are available in a variety of diameters and lengths. They can be either plain or fluted. Fluted balusters have a decorative groove that runs along the length of the baluster.
To install balusters, you will need the following tools and materials:
- Balusters
- Baluster spacers
- Screws or nails
- Drill
- Countersink bit
- Tape measure
- Pencil
Follow these steps to install balusters:
- Determine the spacing between the balusters. The spacing between the balusters should be no more than 4 inches.
- Mark the location of the balusters on the top and bottom rails. Use a tape measure and pencil to mark the location of each baluster.
- Install the baluster spacers. Baluster spacers are used to keep the balusters evenly spaced. Install the baluster spacers on the top and bottom rails.
- Insert the balusters into the baluster spacers. Insert the balusters into the baluster spacers on the top rail.
- Secure the balusters to the top rail. Use screws or nails to secure the balusters to the top rail.
- Install the balusters in the bottom rail. Insert the balusters into the baluster spacers on the bottom rail. Secure the balusters to the bottom rail with screws or nails.
