Hi, cast iron railings around my home are pre-WW1 era, they survived the smelter for the war effort. The horizontal CI flat bar has cracked, so hence the repair. far from being a weld of any significance, but I will post up pics of before and after. Cheers.Be interested to see the weld that they produce. The write-up infers that they are for doing rectifications in cast iron. is this what your project involves. Look forward to some photos as always keen to see work on cast iron.
