Thread: Making a firearm...legalities

very cool, i made one from a small dry powder fire extinguisher. just welded an airline fitting to the top to pressurise it, and some fuel line to extend the nozzle, tied the trigger on, and a tin with diesel/rag for the pilot. then about 60m of air line... just filled the thing with petrol and lit the pilot and walked back to the compressor to plug in the air line.
made a nice effect for a couple dollars of fuel! about a 6x1m pillar of fire straight up (or something like that.... might have been drunk, and it was years ago)
not keen on being anywhere near it though...
