So I got the fence finished. I will get some photos soon. Getting the rails up was relatively easy. I put a clamp on one post, approximately the height I wanted the rail, then with the one end of the rail resting on the clamp I set the other end by securing it with the saddle at the required height. Then I removed the clamp, set a magnetic level on the rail, got the level, checked the height and set that end with another saddle. I had the gate frame in position and ran the rails straight across it. Then I secured the saddles on the fence frame and cut the rail between the gate frame and the posts.
Putting up the fence sheets was a bit more difficult, because I was doing it on my own and the sheets can be cumbersome. I used clamps again to hold things in position. It took a bit of fiddling to get the sheet at the right height and sitting level. Once that was done it was just a matter of running the self drilling screw in through the sheet to the rail. The next sheet is clamped to the previous one and the height and level checked again before screwing the sheet on.
Running the fence around the corner can be done a number of ways. If you can finish the positioning of the sheets so that the edge is just past the corner post you should be able to set the next sheet (around the corner) so that the edges overlap. Another method is to bend the sheet around the corner. I am not sure that this could be done with any pattern other than corrugated. Bending the sheet around the corner is mostly a case of brute strength and gentle persuasion.
Originally I wanted the gate the open onto the sheeted side of the fence, but the gate I used was not designed for that. It could be swung open but the rails would get in the way and stop it opening more than about 45 degrees. I switched the latch around and it now opens the other way.
So the fence is completed and I have put a temporary fence across to the house to stop the animals wandering off.
We have started working on the front garden now, so I will start a new post to document that.
