Making a wooden garden bench with a curved seat requires careful planning, the right materials, and some woodworking skills. Below is a step-by-step guide to help you build one.
Materials & Tools Needed:
Materials:
- Pressure-treated or hardwood planks (cedar, teak, or oak work well)
- Wood screws or bolts
- Waterproof wood glue
- Sandpaper (80-120 grit)
- Wood stain or outdoor wood sealant
- Wood filler (optional)
- Carriage bolts, nuts, and washers (if using a bolt assembly)
Tools:
- Jigsaw or bandsaw (for curved cuts)
- Circular saw or table saw (for straight cuts)
- Drill with wood bits
- Clamps
- Measuring tape
- Pencil & compass (for marking curves)
- Sander or sanding block
- Router (optional, for rounded edges)
Step-by-Step Instructions:
1. Plan and Design the Bench
- Sketch a simple design with approximate dimensions.
- A standard garden bench is around 48-60 inches wide, 18 inches high, and 16 inches deep.
- Decide on the curve: A gentle arc of around 1.5 to 2 inches of drop from the center to the edges is comfortable.
2. Cut the Bench Seat Planks
- Use a compass or flexible batten to mark a gentle curve on each seat slat.
- Cut the curve using a jigsaw or bandsaw.
- Sand the edges smooth to prevent splinters.
3. Construct the Bench Frame
- Cut two side legs (18” tall) and two long stretchers (the length of the seat minus the leg thickness).
- Attach the stretchers to the legs using screws or bolts.
- For additional stability, add a center support stretcher beneath the seat.
4. Assemble the Curved Seat
- Align the curved seat slats on the frame.
- Space them evenly (about ¼ inch gap) for expansion.
- Attach them using screws from the top, or use dowels for a hidden fastener look.
- If using screws, pre-drill holes to avoid splitting.
5. Add Backrest (Optional)
- If adding a backrest, attach two vertical supports to the rear legs.
- Cut a curved top rail for comfort and secure it to the supports.
6. Sand and Finish
- Sand all edges and surfaces smooth.
- Apply a wood stain or outdoor sealant for protection.
- Let the bench dry for 24-48 hours before use.
Tips for a Professional Finish:
- Use a router to round the edges for a smooth feel.
- If the curve is more pronounced, use steam bending or laminate thin wood strips.
- Add armrests for extra comfort.
