Posted Fri Jun 17, 2011, 6:03am Subject: Boiler leak/crack repair
Well, my NS Oscar problems keep popping up. I thought the steam leak was around the threads of the boiler safety valve so I used some JB Weld water sealant on it and it still leaked. I looked a bit closer and found the reason for the leak...see pic.
Keep in the mind, the boiler looks terrible because I removed the insulation that was already flaking off so most of that grunge is glue residue. So now it would appear a heating torch, some flux and some solder are in my future.
Anyone ever experience a solder repair on a boiler like this? Any advice?
It is hard to see on mt tiny phone screen but hard soldering is not a hard thing to do. The parts need to be VERY clean. Use a non toxic flux and lead free solder (available at the hardware store). Don't over heat the boiler, this is a comon mistake beginners make. When the flux starts to smoke, take off the heat and apply the solder, that should be all it takes for most solder repairs.
