than the Sievert torch went out and was very tricky to relight again in the 'heat' of the moment . I struggled with this for a while, particularly with the fiddly and counterintuitive bottle regulator that came with the torch. At this point I was acutely aware that all the time the boiler was losing heat,Half an hour later I fished the boiler out of the pickle to look at it. Imagine my surprise when I saw that the joint in question had formed into a smooth, round pristine collar of silver solder round the neck of the tube. It's now the best-looking joint on the boiler, and unless anything else opened up with the heat (and I have no reason to think that happened) it may be that the boiler is now intact.I say 'may be'. It went straight back on to my hydraulic testing rig. When I upped the pressure I noticed a leak from where the neck of the adaptor I had made for the test pressure gauge was screwed into the boiler bushing so I took a spanner to tighten the adaptor ... and sheared off the threaded section at the end!
Am I completely useless or is this normal for beginners?
