"Can you make me some walls please?".
The long gradual curve on the middle picture is always the difficult bit as it is difficult to keep the curve regular and even batter with the correct width at the top.
I'm quite pleased with the result. Although it is only a small amount of walling there are 4 wall ends and 3 corners in total. Just to add to the small difficulty of making the curve I also had to make the wall around the curve gradually reduce in hight to make it end at top rail of the old gate.
