Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
You will need to build two arms. I used the Kreg Jig with pocket holes set for 1 1/2" stock and 2 1/2" pocket hole screws and glue.
Once the two arms are built, attach front and back aprons, and backrest support. I again used the Kreg Jig and 2 1/2" pocket hole screws and glue. Adjust for square.
You can click any image for a larger view. The front cleat is a 2x2 and needs to sit 1/4" down from the top of the front apron. The back cleat is a 2x3, and sits flush to the bottom.
Side note - if you would like to increase the weight capacity of this sofa, simply add 2x4 "legs" to the 2x4 seat support, they would be about 9" long, and would just be screwed to the side of the 2x4 seat support, and act as hidden legs right where you might need them.
The trim just makes things prettier. I used a nailer and glue.
Begin by marking the location of your slats and predrilling pocket holes set for 3/4" stock. Join using 1 1/4" pocket hole screws and wood glue. If you wish (we choose not to) you can round the top edge of the back with a jigsaw. Sand until smooth.
Now the fun part! Slide the back in place, and then screw to the two 2x4s as shown above in the diagram. Make sure you use a countersink bit.
It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.
