Roughly
mark the position of the posts for the ends and any bends of your fence (1, 2 and 3 shown on figure). You now have the straight
runs roughly identified. Look at the slope of the ground and mark any point where the angle of the ground level changes significantly
(4 on figure). These are the main points where there MUST be posts.
Cut
timber posts post and stay(s) so that the stay can be inserted into the post (figure right). Concrete posts and stays have the
joints cast into them during manufacture. When using angle iron, drill holes so that each stay can be bolted to the post.
