Quick Tip: How to hammer a nail straight

If your nails keep bending when you are hammering, check the head of your hammer. It could be that the face has picked up some dirt. This causes the hammerhead to slip slightly when it hits the nail. To solve this, give the head a clean by rubbing it on some sandpaper or a bit of rough concrete.

  • Step 1. Have your timber pre-cut at Bunnings

    To make this D.I.Y. project even easier you can have your timber cut at your local Bunnings. The cutting list for this project is:

    17mm x 1.2m x 2.4m form ply:

    • 600mm x 550mm x 2 (box side)
    • 1200mm x 550mm x 2 (box side)
    • 1200mm x 600mm x 1 (base)

    90mm x 19mm merbau:

    • 1240mm x 6 (front and back)
    • 600mm x 6 (each side)

    70mm x 35mm structural pine:

    • 1200mm x 2
    • 600mm x 2

    140mm x 45mm treated pine:

    • 565mm x 2

  • Step 2. Pre-drill the holes for the box

    Use the 2.5mm drill bit to drill holes in the edges of the 600mm x 550mm form ply and the 1200mm x 550mm form ply. Drill four holes in each side. Make sure the pre-drilled holes go through the centre of the material that you’re going to be joining it to.

  • Step 3. Screw the box together

    Use the 30mm outdoor screws and the drill to join the box together. Before screwing make sure the edges of the box are flush.

  • Step 4. Measure and mark the recess for the struts

    Use the set square to measure an 8mm recess for the struts for the casters. Put the struts in place.

  • Step 5. Pre-drill the holes for the struts

    Use the 2.5mm drill bit to drill the holes to secure the struts. Drill two for each 45mm end and three along the 140mm side.

  • Step 6. Secure the struts

    Use the drill and the 50mm outdoor screws to secure the struts to the planter box.

  • Step 7. Measure and mark for the support frame

    Measure and mark where the support frames will go. Ours will sit about halfway down the box, which is 300mm down from the top.

  • Step 8. Secure the 1200mm support frames

    Place one of the 1200mm pieces of timber on the mark that’s on the inside of the planter box. Use the drill and three 50mm screws to secure the timber to the box. Repeat this for the other side of the planter box.

  • Step 9. Secure the 600mm support frames

    Then secure each of the two 600mm pieces of timber on opposite sides with two screws.

  • Step 10. Cut the form ply base

    Use the mitre saw to remove the corners of the base for the planter box at 45-degrees. This will allow for drainage.

  • Step 11. Secure the base

    Put the base in place. Use the nail gun to secure the base to the support frame.

  • Step 12. Drill drainage holes

    Use the 10mm drill bit to drill drainage holes in the support frame. We drilled eight.

  • Step 13. Attach the merbau cladding

    We had the cladding for our planter box pre-cut at Bunnings. Take a piece of the 600m cladding and place it on one of the sides at the bottom of the planter. Use the nail gun to secure it, with two nails at each side and one in the middle.  Place two pieces of Masonite packer on top of this piece of cladding and put another piece of cladding in place. Use the nail gun to secure it. Repeat this to attach the cladding to all four sides.

  • Step 14. Attach the caster wheels

    Use the 40mm screws to attach the caster wheels to the base. Make sure you’ve allowed enough room for them to be able to swivel.

  • Step 15. Measure and mark for the border

    Place the timber for the merbau border along the edges of the planter, allowing for a 20mm lip. Use the combination square to measure and mark the four pieces of timber.

  • Step 16. Cut the border

    Set the drop saw for a 45-degree mitre cut. Cut the ends of each piece of timber for the border.

  • Step 17. Nail gun and glue the border in place

    Put the borders in place, making sure they’re centred and the ends are flush. Use the nail gun to attach the borders. Apply glue to the joins and wipe away any excess.

  • Step 18. Attach the weed mat

    Cut the weed mat to size to fit the base of your planter box. Use the nail gun to secure it.

  • Step 19. Just add plants (and water)

    And there you have it, a fantastic moveable planter box. Just pour in some quality potting mix and plant your favourite flowers, herbs or vegetables.

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 which 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.
