I had some welding done once and at the shop, which was outside, there
were a couple of gas tanks that needed repairs. The gas tanks were first
filled with hot water, left to sit for 10 minutes or so, then drained.
Then, they would light a sheet of paper rolled up and give it to a guy who
would run past the tank and shove the lighted paper into the filler
nozzle. The tanks I saw went *whump* and had 2 feet of flame, but did
not distort. Then the welder went at it with oxy-acet. I was suitably
scared sh*tless when I saw what they were going to do. But evidently
this was common practice. The gasoline sold there was 72 octane - not
very volatile, actually, and the altitude was 7600 feet.
found this for ya nick....:wink:
I am sure Gary is pretty fast on his feet..
