BB Said:........................ "I to feel that we should not be discussing welding of fuel tanks here on this platform".
I have to disagree with this sentiment. If someone is considering welding a tank then they should be able to come to a forum such as this and see the pro's and cons of attempting it. They should be able to read the discussion on its safety , how dangerous it might be, the legal ramifications and so on. They should be able to make up their own minds, using the information gained in places such as this and other places, to make their decision. Anything else is a form of censorship. There's enough of that nanny state stuff already.
