As you can see from the wall photo, the wall has sunk so the fence will bri dge that and I'm planning to install it using resin fixings with nuts both above and below the fixing plates. I might fill in the gap with wood or som ething to make it look a bit less obvious that the post doesn't meet the wa ll.
Inevitably the bits of old cast iron shown will get in the way at some poin t so I'm wondering about the best way to remove them. Will the break off if I just hit them with a hammer? How about a multitool with a suitable blade ? I'd rather not have to do it manually with a hacksaw with blue blade!
