Now, just to show off a little, even I felt I'd surpassed myself with the tidiness of the weld itself. No angle grinding was used at all to cover mistakes.
Since it was always going to be a very small weld, I judged that using a stick weld would add far too much metal and need grinding away afterwards to tidy it up leaving iron filings all over the place to rust. It would also be very difficult to wield the stick in such a confined space above the boiler. So I decided to use a TIG torch.
It was still not an easy task as, not only did I have to get the welder in the cab but an Argon gas bottle as well. There really is very little space in this cab!
It was a good decision, however, as the top photo shows.
