1. Plan - Measure Your Space
The Porch Swing frame built here is made with a 6-foot 4x6 beam and 4 - 90" long 4x4 legs. With these sizes the frame will measure 82" high to the top of the beam, and the footprint will be 100" deep and 86" wide. You can adjust these sizes as needed, and just have the hardware store do these straight cuts so that you do not need to do any cutting yourself.
2. Purchase Materials
Order the A-Frame Brackets first, they will take 2 to 7 days to arrive. Most of the parts from Amazon will arrive in 2 days. And many things can be sourced locally--See the Materials List above.
3. Stain & Soak Lumber
Stain the Lumber. Do not stain the last two inches of one end of the 4x4 lumber. Then after stain dries, stand the 4x4 lumber upright in a plastic container and soak the unstained ends for 3 to 12 hours in a wood preservative.
4. Attach A-Frame Brackets
First attach brackets to 4x6 beam. Then attach all legs to brackets while frame structure still lying on its side on he ground.
5. Attach Swing Hangers to Beam
Predrill holes where swing hanger lag screws will be installed with a drill bit that is smaller in diameter than the lag screws. Attach swing hangers with lag screws.
