HERE'S HOW:

Preparation

Cut all the required 25-degree angles as indicated in the cutting list above. Confirm the direction of angles before cutting by browsing the images below. Some pieces have left-left (mirror) angles and others left-right (opposite) angles.

 

1. Drill two pocket-holes at the top of each of the four legs.

2. Mount the legs 150mm in from the bottom of the front and back seat frame. Use wood glue and 32mm pocket-hole screws to secure in place.

3. Place a seat arm on top of the front seat frame (back) - aligning the bottom of the seat arm with the angle of the leg and the end of the seat frame. Use a 24mm spade bit to drill a hole completely through the arm and to a depth of 15mm in the back of the front seat frame. Repeat this for the other side of the front seat frame and also for the back seat frame.

GOOD TO KNOW: Wrap a piece of masking tape around the spade bit to the total depth that needs to be drilled.

4. Align the arm side to be in line with the seat frame and drill a second hole 25mm in from the first hole. This hole is used to support the arm side in upright position.

5. Cut the 25mm dowels into 4 lengths of 568mm. Insert through the first hole drilled in the seat arms. Pre-drill a 2.5mm pilot hole and secure in place with 3.5 x 40mm screws.

GOOD TO KNOW: Allow a 15mm overhang on both sides of the arm sides for fitting into the drilled holes in the seat frame.

6. Now you can attach the arm top. Drill two pocket-holes at the ends of each arm top and secure inside the arm sides with 32mm coarse-thread pocket-hole screws and wood glue.

GOOD TO KNOW: Use an offcut to hold the arm top in place as you secure with screws.

GOOD TO KNOW: Before attaching the seat slats, place the assembled arm sections in position. These will be loose until you secure the slats in place.

7. Drill 2 pocket-holes at both ends of the seat slats.

8. Attach the seat slats to the back side of the front and back seat frames. The slats are flush with the top edge of the seat frames. Start with the first slat at both ends and space the remaining slats in between.

9. Drill two pocket-holes at both ends of the seat frame side, leg support and secure this 80mm up from the bottom of each leg with wood glue and screws.

10. Assemble the seat back using wood glue and pocket-hole screws. The centre and side pieces are attached to the two main uprights.

11. Once assembled, secure the seat back to the seat frame using wood glue and pocket-hole screws.

GOOD TO KNOW: Clamp the back to the seat frame to make it easier to join.

Finishing

Sand all the pieces smooth with 120-grit and then 240-grit sandpaper and round-off all the sharp edges.

Apply a clean, polyurethane sealer, oil or wax to protect.
