A short look at the parts to make a DOOM BFG like in the movie. Just a typical Tuesday here in Killbucket-Land. I'm making single and dual miniguns, in short and long models. these are motorized dummy guns that spin at up to 900RPM, and are 18volt powered. There is a hollow shaft in the middle to allow somebody to put any airgun, watergun, bubble-gun, whatever, inside so it fires out the center axle. http://www.killbuckets.com
