To make this project easier, you can have most of the timber cut at your local Bunnings Warehouse. The cutting list is:
150mm x 25mm Treated pine (for the boxes):
70 x 35mm Treated pine (for the legs):
Always wear gloves when working with treated pine. While most of the timber has been pre-cut we still need to cut the short ends for the sides of the planter boxes. To do this, measure and mark the timber to 150mm.
Use the drop saw to cut six of these 150mm ends for the planter boxes.
Take a length of the 1200mm timber and lay it vertically. Take a 1350mm piece of timber and align it with the top of the 1200mm and to the right, at roughly a 30-degree angle. Measure and mark 510mm and 935mm from the top of the 120mm piece of timber. Lay the middle support at the 510mm mark and the bottom support at the 935mm mark. Make sure the supports are square. Mark where you can drill to join the supports to the frame.
Put the middle support on the 1200mm timber at the 510mm mark. Use the drill and a 50mm pine screw to secure the support. Check that the supports are square. Once they are square, attach the supports with the drill and pine screws to the 1200mm piece of timber.
Use the square to make sure that the 1200mm timber and 1350mm timber are still square. Once they are, secure the supports to the 1350mm with the pine screws. Repeat the above steps to build the second A-frame, making sure it is a mirror image of the first one.
Take a 1m piece of the 150mm x 25mm and stand it on the bench on its narrow edge. Take a 150mm end, place it behind, and flush with the 1m piece of timber. Secure the 150mm end to the 1m piece of timber with a nail gun. Repeat this at the other end. Place the second 1m piece of timber next to 150mm ends. Make sure it's flush and secure it with the nail gun. Repeat this to make the two other planter boxes
With the planter box on the bench, take a 900mm piece of timber and place it inside the planter box. The base is shorter than the length of the box so that water drains away at either end. Tap the base so that it's flush with the bottom of the planter. Turn the planter on its side. Use the nail gun to secure the base to the sides of the planter box. Repeat this to attach the two other bases to the planter boxes.
Use the 3mm drill bit to pre-drill two holes at both ends of the 1000mm timber, which is the back brace. Attach the back brace to the A-frames using the 50mm pine screws
Place a planter box on the bottom supports on the A-frames, making sure it's square. Pre-drill two holes in either side of the planter box with the 3mm drill bit. Then use the 50mm pine screws to secure the planter box to the A-frames. Repeat this process to attach the two other planter boxes.
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. 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.
