Cast Iron Step Repair

This is a broken Cast Iron landing step for an old spiral staircase.




 Edges of the crack ground out to a "vee".

 First attempt at welding - stick welded using Nickel based rods. Pretty horrible - old rods, possibly wrong power setting, out of practice & even though these rods are meant for "cold" welding, it probably would have come out a lot better if the casting had been pre-heated.

 After grinding out a lot of the Nickel stick welding, I tried again, this time TIG welding using Phosphor Bronze rods.

 The welds on the under side were left.

 The ones on top ground smooth

Ready to be sanded all over before re-painting.
