This project was built and designed by Jay Bates. It’s a simple yet thoughtfully designed porch swing made entirely from 2x4s, combining strong joinery, smart layout, and smooth finishing to create a comfortable and lasting seat for any outdoor space.
The design focuses on affordability, ease of construction, and comfort. With a little planning and a few shop tools, this project can be completed in a weekend—and used for years to come.

Planning and Workspace Setup
Jay begins the project by organizing his workspace and setting up his tools for efficiency. He places his planer in a dedicated infeed/outfeed area to streamline stock preparation, making the process smoother from the start.
The main material for the build is standard 2×4 lumber, which is inexpensive and easy to source. The total cost is around $40, and with a bit of focus, the swing can be completed in about five hours.
Milling and Shaping the Lumber
The first task is trimming down the 2x4s to uniform widths, which helps ensure clean joints during assembly. Any rough edges or inconsistencies in thickness are removed, giving Jay a set of clean, square boards to work with.
With the stock milled, he moves on to shaping the angled half-lap joints. These joints form the swing’s arm assemblies and are key to its strength and stability. Maintaining the correct orientation of the pieces is important here to ensure a snug fit.
Using the Right Tools for Precision
Jay uses a dado stack on his table saw to cut the half-lap joints accurately. This tool setup allows him to remove just the right amount of material from each piece, resulting in tight, supportive connections that won’t shift or loosen over time.
To speed up repeatability, he creates a stop block. This helps maintain consistent depth and position for each joint cut, ensuring all matching parts align correctly without measuring each time.
Assembling the Arm Sections
Once the joinery is cut, Jay glues the arm assemblies together and allows them to set. This glue-up stage is essential for overall structural integrity, giving the swing the strength needed to support full body weight.
After the glue dries, he refines the shape and smooths out any glue squeeze-out or misalignments. These minor adjustments give the arms a finished look and eliminate anything that might interfere with the seat slats or fasteners.
Building the Seat Support System
Jay then cuts additional pieces to serve as supports for the seat slats. These are ripped from the same 2×4 stock and attached to the inside of the swing’s arm frames.
This framework distributes the weight evenly and gives each slat a secure place to rest. It also helps create the gentle curve and spacing that make the swing so comfortable to sit in.
Slats, Spacing, and Smoothing
Each slat is run through a round-over bit to ease the top edges. This not only improves the visual appeal but also makes the seat more comfortable—no sharp corners to dig into your legs.
Before installation, the swing is flipped upside down, making it easier to work from the bottom up. Jay starts from the front of the seat and works backward, using a drill bit as a spacer to ensure even gaps between each slat.
Screws are driven in securely, and care is taken to maintain symmetry on both sides of the seat. It’s a simple technique that ensures a polished result.
Final Sanding and Installation Hardware
Once all the slats are attached, Jay gives the entire swing a final sanding. This step eliminates any remaining roughness and prepares the surface for finish or outdoor use as-is.
He then installs heavy-duty eyebolts, anchoring them through the arm assemblies and into the support structure below. This provides strong, safe mounting points for the hanging hardware, allowing the swing to be installed on a porch or from a sturdy tree frame.
Ready to Relax
Though the video doesn’t show the swing in use, it’s built with enough length and depth to be genuinely comfortable. It’s a practical, budget-friendly design that delivers on both appearance and performance.
Jay’s attention to clean joinery, thoughtful spacing, and comfortable shaping ensures the swing is not only functional but enjoyable to use.
A Solid Outdoor Project with Great Value
This porch swing demonstrates how a handful of 2x4s and some careful work can result in a standout piece of outdoor furniture. It’s durable enough for daily use, simple enough for intermediate builders, and satisfying enough to be worth repeating.
For woodworkers looking to build something useful and beautiful, this swing checks all the boxes—and it’s a great gift idea too.
