Eventually after going around +- 6 times, nice and slowly, heating evenly using flux as needed, and bearing in mind the other join was first time lucky, and getting the same sickening result every time.
I ended up strapping the barrel together length ways, as I had done for the initial weld on both joins, thinking that it may help and ended up-with a bigger bang on cooling... and yes, I was adding s#$# loads of rod by now thinking more would hold... What a waste of such good rods :crying-blue:

So at this stage, and after spending more time than I should have threw in the towel, wrote the time and money off as school fees and bought a nice shiny 5l boiler from our trusty supplier... my reason for building a 100 was to speed things up as my time is limited. I love to tinker, but am obviously missing something with this second join, less room to flex I guess as both sides are now joined??
So I guess the moral of the story... STOP while you are ahead, and don't be greedy !!!
