8 Hints and tips
  • Step 1. Build a work bench

    Having a sturdy work bench is a necessity to any working area.
  • Step 2. Prepare the materials

    Mark the timber to length using a carpenter's square and a pencil, then cut the timber with a circular or hand saw. (Note: it is recommended to label each piece, e.g., right leg, etc)

  • Step 3. Build the end frames

    Gather the four legs, two bottom and two top cross bars. Position one bottom cross bar 100mm from the leg base and at right angles then drill two holes through the cross bar and leg. Now coach bolt the cross bar and leg loosely together, so that the bottom cross bar is inside the legs – repeat for the other bottom cross bar. For the top crossbars, follow the same procedure making sure that they are on the outside and flush with the top of each legs before drilling and bolting.
  • Step 4. Attach the bench top rails

    One at a time, position the bench top rail flush against the inside of the leg and the top of the end frame then drill two holes through the leg and bolt together. Now attach the remaining end and repeat for the other rail.
  • Step 5. Attach the bottom planks

    Again one at a time, place a bottom plank tight against the leg and flush with the outside edges of the bottom rails, then secure with wood glue and 50mm nails. Repeat with the remaining plank leaving a gap between the two planks.
  • Step 6. Attach the bench top planks

    Take one plank and place it flush with the end of the top cross bars with 300mm hanging over the frame at each end. To attach the planks, apply wood glue to the top cross bar and then drill two holes through the planks and cross bar 60mm in from each plank edge. Now bolt and repeat.
  • Step 7. Adding a finish to the bench

    In this final stage, you may want to consult with Bunnings for advice on what paints or oils would be the most appropriate for your bench.
  • Step 8. Hints and tips

    When cutting with a circular saw, a good idea is to have the top side of the timber face-down. This will leave the top side with a smoother edge along the cut.

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint Test.
