R14 is expensive and so destructive.
Expensive yes, destructive no. It's a green gas as far as i've read and been told.
As for modify a torch, actually the thing I Have now is not a torch. I'd say modifying the torch end of a... torch. Would be dangerous, you could easily create a bomb, however, cutting off the fitting is not exactly dangerous to those around you.
I agree that its not a jab persay, however I don't like the way it was stated.
