6 Hints and tips
  • Step 1. Choosing materials

    You have lots of options when choosing materials. You could simply tie a rope to a tree branch and use an old tyre or build this one which needs a bit more time and effort.
  • Step 2. Where to begin

    Firstly find a good piece of level ground and make sure the surrounding area is well clear from trees and fences and within view from the house. Now lay out the crossbeam and mark out each end for your post holes. Measure 2.15 metres from the ground up and hammer a nail into the pole.
  • Step 3. Concreting poles

    Dig two holes 800mm-900mm deep and 250mm wide. Lay a shovelful of gravel for drainage, insert poles and check that they sit level. Half-fill the holes with water, pour in the pre-mixed concrete and mix with shovel to release air bubbles, then re-check that the poles are level. It takes about 24hrs for the concrete to completely dry, so be careful not to move or knock the poles.
  • Step 4. Swing measurements

    Place your toddler swings on the ground. Mark on the crossbeam even spaces between the posts and each swing. Drill four holes through the longest side of the beam (150mm), insert the eye bolts and tighten while the beam is still on the ground. Measure 2.15 metres from the ground up and hammer a nail into the upright pole, repeat on the opposite pole. Sit the beam on the nail and check to make sure it is level. If level, clamp the beam and the posts.
  • Step 5. Attaching the swings

    Drill two holes at each end of the beam, evenly spaced. Bolt the cross beam to the posts and tighten. Lift the swing's ropes to both eye-bolts and attach using the four bolted shackles. You may require a ladder. If you've made your own swing seat, attach it with a chain to the eye-bolts with the same shackles, and remember that the right seat height for toddlers is about 450mm, depending on age.
  • Step 6. Hints and tips

    Double check to make sure all nuts and bolts are tight and secure, and it’s a good idea to use a wood preservative or paint the exposed ends to keep out rot or termites. As the kids get older the swings can be adjusted by using different seats and chain lengths.
