Swing between two posts


As with most families in the UK we have a relatively small garden. But of course we want to provide fun toys in the garden for the kids to play on.

Initially I am installing a set of removable posts so the garden can be configured for different purposes. One of my first problems was how to rig a swing between 2 posts ~4m apart. The solution is a trianglated rope swing.

The top rope forms two triangles providing support points at approximately the width of the seat, thus the seat can be made stable with respect to side to side motion. Snap shackles are used to clip the swing to eye bolts in the posts. This makes the swing easily removed. One extra snap shackle is used to join the ends of the top rope in the middle. The swing seat is supported conventionally below the top rope triangles. The posts need support bases that extend 2feet or more below ground as they have to act as canteliver supports.
