Huh, this has turned into an accident story thread already. I think the only gun-related injuries I've had were the constant cuts on my hands and arms from sharp-edged hose clamps prevalent in my designs. And probably some propane burns.

I learned to always wear safety glasses shortly after making my first bbmg, though.

Not really sure how I manage to avoid getting hurt, since I'm normally rather apathetic to dangerous practices that are not likely to result in death/blindness.

One of my favorite things that scares the hell out of people is cutting a 20-pound propane tank in half without purging it first :D

Neither would I.
'Not purged' meant that the tank still has gas in it, not that the gas is above atmospheric pressure.

Cutting through a pressurized tank would most likely just cause it to vent violently rather than explode. Sparks from a small angle grinder aren't usually intense enough to ignite propane, but I wouldn't put money on it in this case.

i wouldnt cut it, with any spark involved, even if the spark might not be strong enough to ignite the gas, i wouldnt wanna test it to find out!!!
