hence my "if i have to warn you about how to cut open a propane tank you shouldn't be casting. "
that's not directed at you Savage78, unless you would just willy nilly cut an propane tank in half without checking for any gas lol.
i would chop a tank in half after making emptying it with a sawsall or bandsaw as it's not going to spark or make enough heat to ignite any residual gas.
People were playing with molten lead thousands of years before the advent of gas bottles
Except that bandsawing will generate heat, and on a small enough scale, high temperatures. Once you cut through the tank wall, you introduce air (oxygen), and have a potentially combustible mixture. The hot spot at the tooth and swarf that just came off is the third leg of the fire triangle.
There was another thread about this awhile ago......
If done properly you won't generate enough heat to cause that to happen and you would need to be pushing really hard to generate that much heat to cause it to smoke. The common sense would be to go slow so you don't generate any heat as well as to use a coolant to cool it down and to also lubricate the blade so it will cut through the tank with ease.
There. ^
Common sense.
My point in posting #26.
Don't get me wrong, nothing better than asking if one is not certain.
Lord knows i've pulled some boner moves ...
y'all
