thought as much - threads can and do explode
posters - please take care when handling volatile topics.
flashpoint can easily be reached, especially when excessive agitation is present and the gas content is excessive.
Dust explosions can prove deadly. You could end up with egg on your face.
Seemed like a good idea at the time!!!
I reject your reality, and substitute my own!
Well I've just opened and read this thread.
Another fine example of how this microcosm of the general population know sod all about everything, and then when someone who does know (Nigel - Refueler) explains don't believe him anyway.
I too have (gas) welded diesel tanks on Transit motorhomes without problems.
However I was arc-welding a grass-track racer one evening when the motorbike fuel tank it was fitted with caught fire. I don't know if an arc occured in the tank or the vapour just ignited from the site of the weld, but it made Standard Fireworks Roman Candles look very feeble.
Another person's thoughts about you are outside of your jurisdiction.
Coming late to this debate, I am firstly alarmed at the "pour some diesel in a pan and set fire to it to prove that it does not explode" approach. The same would apply to most flammable substances.
The important point is that diesel deposits "residues" which are of higher molecular weight than diesel oil per se, onto the walls of the tank. How they react with oxygen and a spark is your guess not mine.
For safety reasons I would agree with a mechanical method to cut the tank, not a grinder which creates heat and sparks.
At the end of the day if you go ahead and blow the back off the boat, what are you going to tell your insurers? ( and the wife?)
