We have a 250m stretch of fencing to take care of this summer. It’s full of tree’s, uneven ground and water. If we can fence this, we’ll have learned something valuable.






Rough Notes

We need strainer posts and fence posts

Make a template on a length of batten to indicate sink depth, fence height and both barbed wire lines. Transfer these measurements to each post before boinking.


Strainer Posts




Strainer posts: Strong posts with diagonal supports, called stays, that take the tension of the fence, stopping all of the fence posts from being pulled in one direction or the other.



  • 2.4 x 100 x 100 supported by diagonal struts dug into the ground
  • Dug in, to a depth of at least 90mm (preferably a meter) and properly tamped down.
  • Strainer posts should be placed at every change in direction or gradient
  • Traditional method for straining posts is to inset 2×4 horizontally into the post to stop it turning in the ground.
  • Stays should connect to the strainer post a minimum of 750mm from ground level
  • Stays should be notched at least 75mm deep into the straining post
  • Anti turn device should be inset around 150mm from the bottom of the post. You can use 2 x 4 or a quarter of a post.

Fence Posts

    • 1.8m x 75mm x 75mm
    • Minimum depth of 550mm

    Barbed Wire

    •  Positioned 125mm above wire fence. Second strand 125mm above this.
