Once I had all the arch stones mortared in place, I ran an oak timber on the inside behind the arch to finish spanning the opening. Further dry stone was then added in courses as usual. I wanted two or three shallow courses of stone above the arch to reach the final height.
The image on the left below was taken from the old balcony and the image to the right is a good illustration of ‘the Double’ – one line of face stones to the outside, and a second to the inside, with the middle filled with smaller locking stones.
And the view from the front……………….almost finished. I’ll need to find a solvent or some other method for removing the painted numbers on each of the arch stones. The farmer I bought the arch from had marked each stone as he’d demolished it. Essential maybe, but now, 10 years on, maybe not so easy to get rid of.
