To begin with, stairs serve as a vital element in any building, and the stringers play a crucial role in providing stability. To make stair stringers, you need to have a good understanding of the primary concepts of carpentry and precise measurements. Once you have the necessary information and equipment, you can create strong and appealing stair stringers without having to hire a professional. This article will guide you through the process of making stair stringers, ensuring you end up with a beautiful and sturdy staircase that will last for years to come.

How to Make Stair Stringers: Steps and Tips

Making stair stringers can seem like a complicated process, but with the right tools and techniques, anyone can create sturdy and safe stairs for their home. In this section, we’ll outline the steps you need to follow to make stair stringers, along with some tips and tricks to ensure your stairs are functional and beautiful.

1. Gather Your Materials

Before you start making stair stringers, you need to gather all the materials you’ll need. This includes lumber for the stringers, wood screws, a saw (preferably a circular saw), a framing square, a level, a drill with a countersink bit, and safety gear like eye protection and gloves.

2. Measure the Rise and Run

The rise is the height of each step, while the run is the depth of each step. You’ll need to measure both to determine how long your stringers should be. Make sure to measure from the top of the landing to the bottom of the proposed stairs, and then divide by the desired step riser height.

3. Determine the Stringer Angle

The angle of your stringers will depend on the height of your stairs and the run of each step. To determine this angle, you’ll need to use a framing square and a level to make sure your stringers are at the proper pitch.

4. Cut the Stringers

Once you’ve determined the angle of your stringers, it’s time to start cutting. You’ll need to use a circular saw to cut the stringers to the proper length, using your measurements from step 2.

5. Install the Stringers

Next, you’ll need to install the stringers. This involves placing them in position against the side of the deck or landing and securing them in place. Make sure to use wood screws to attach the stringers securely and make sure they’re level.

6. Add Support Blocks

To add additional support for your stairs, you’ll need to install support blocks between the stringers. These blocks should be cut to fit and then secured in place with wood screws.

7. Cut the Stair Treads

Once your stringers are in place, you can start cutting the stair treads. Remember to measure and cut each tread individually to ensure a proper fit.

8. Install the Stair Treads

After you’ve cut all your stair treads, it’s time to install them. You’ll need to attach them to the stringers using wood screws and ensure they’re level and secure.

9. Add a Stair Railing

To ensure the safety of anyone using your stairs, you should add a stair railing. You can purchase a pre-made railing or create one yourself using lumber and a drill.

10. Finish and Stain Your Stairs

Finally, you’ll want to finish and stain your stairs to protect them from wear and tear and to enhance their beauty. Make sure to use a stain that’s specifically designed for outdoor use, and follow all manufacturer instructions for the best results.

Making stair stringers may seem overwhelming, but by following these steps and tips, you can create a beautiful and functional set of stairs for your home. With the right tools and some patience, anyone can make stair stringers like a pro.

Choosing Your Materials for Stair Stringers

When it comes to building stair stringers, choosing the right materials is crucial to ensure your stairs are both safe and sturdy. Here are some things to consider when choosing your materials:

Lumber

The most common material for stringers is lumber, with 2×12 being the standard size. The quality of the lumber you choose will impact the durability of your stairs, so be sure to select pieces that are free of knots and other defects.

Pressure-Treated Lumber

If your stairs will be exposed to the elements, consider using pressure-treated lumber. This type of lumber is specially treated to resist rot, decay and insect infestation.

Composite Materials

Composite stringers are an option for those who want a low-maintenance option. Made from a mixture of wood fiber and plastic, these materials won’t warp or rot and require no painting or staining.

Metal

Metal stringers are a popular choice for contemporary designs. These stringers are typically made of steel or aluminum and are very durable. The downside is that they can be expensive and may require a professional installation.

Cable Railings

If you’re going for a modern look, consider pairing metal stringers with cable railings. This style features steel cables that run between the treads and create an open, airy feel.

Glass Railings

For an even sleeker look, consider pairing metal stringers with glass railings. Glass railings create a sophisticated look that is perfect for modern homes.

Stringer Hangers

Stringer hangers are metal brackets that attach the stringers to the upper landing. They provide extra support and stability and are a worthwhile investment for any stair project.

Building Codes

Before starting your project, be sure to research your local building codes. These codes set requirements for stair width, height, tread depth, and railing height, among other things. Your stringers must be built to code to ensure safety and avoid fines or legal issues.

Tools

Building stair stringers will require some specialized tools, such as circular saws, jigsaws, and framing squares. Be sure to have these tools on hand before starting your project.

Safety First

Finally, ensure that you take appropriate safety measures when building your stair stringers. Wear proper safety gear, such as goggles and gloves, and follow the manufacturer’s instructions for all tools and materials. Building stairs can be a dangerous task, so proper safety precautions are a must.

Calculating the Rise and Run of Stair Stringers

Before making your first cut, it’s essential to accurately calculate the rise and run of your stairs. The rise is the height between each step, while the run is the length of each step. Knowing these measurements will help determine how many stairs you need and how high each one should be. Here’s how to go about it:

Measuring the Total Rise

The total rise is the height from the finished floor level to the top of the landing or deck where the stairs will end. To determine the total rise, use a tape measure to measure the distance from the top of the floor to the top of the landing or deck. Make sure to measure at the highest point where the stairs will end.

Calculating the Number of Treads

To calculate the number of treads, divide the total rise by the desired height of each riser. A recommended height for each riser is between 6 and 8 inches. Divide the total rise by 7 inches to get the number of treads you’ll need. If your total rise is 84 inches, for example, you’ll need 12 treads.

Determining the Run of the Stairs

To determine the run of your stairs, use a tape measure to measure the distance of the landing. Then, divide the distance by the number of steps you need to build. This will give you the approximate length of each step. Be sure to add several inches to the length to account for the nosing or overhang of each tread.

Testing the Layout

It’s always a good idea to double-check your layout before you start building. Lay out the stringer on the ground using a carpenter’s square and test the height and tread run by placing a temporary stringer in position. If everything checks out, you can proceed to cut the stringers.

Using a Stair Calculator

If you’re not confident in your maths skills, you may want to use an online stair calculator. These tools can quickly help you determine the rise and run measurements based on the size and angle of your stairs. Simply input your measurements into the calculator, and it will give you a list of the necessary cuts and materials needed to build your stairs. This option can save you time and stress, especially if you’re a beginner in woodworking.

With a little bit of preparation and attention to detail, making stair stringers can be an achievable task for DIY enthusiasts. Calculating the rise and run of the stairs is the first and most important step in the process and requires accuracy and patience. Whether you choose to calculate your measurements manually or use an online stair calculator, double-checking your layout is always a good idea. Next, we’ll cover the steps involved in cutting and assembling your stair stringers.
