Step 2: Smooth the Lumber

Use a jointer and planer to smooth out the rough edges of your Cedar. If you don’t have a planer, you can leave the lumber at its original thickness.

Step 3: Cut the Parts

Now that your lumber is prepared, it’s time to cut the parts for the chair. Set your table saw to the appropriate bevel angle for the parts that require it. For the leg parts, ensure that you create a bevel at the base to form a built-in foot.

Step 4: Assemble the Leg and Arm Assembly

Lay out your parts to ensure everything fits correctly. Mark the screw placements and use a drill press to create holes for your screws. This project will utilize butt joints secured with 5-inch long Spax Powerlags.

Step 5: Glue and Clamp

Apply wood glue to the ends of your parts, then clamp them together, ensuring they are properly aligned. Let the glue set before proceeding.

Step 6: Plug the Screw Holes

To hide the screws, use a plug cutter to create wood plugs from the same or a contrasting material. Insert these plugs into the screw holes using wood glue, and then trim any excess material.

Step 7: Build the Seat and Back Assembly

Repeat the process for the seat and back assembly, applying wood glue and using deck screws to secure the parts together. Consider working with gravity by assembling the back stretcher on the ground.

Step 8: Attach the Seat to the Back Assembly

Align the seat back with the legs and secure it using construction screws, hiding the screws where necessary to maintain a clean look.

Step 9: Add Decorative Features

For an extra touch, consider adding an accented X inside the leg assembly using 1×2 material. Paint it black for contrast and secure it with glue and pins.
