I need to fit a metal fence to a garden wall. The attached photos show an e xample of the fence that's already fitted to another wall plus the wall its elf and the bit of old cast iron fence that remains.
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!
