Hey this looks awesome, I will try to build this. My question is about where and how to get the supplies. I'm good as far as the chicken wire, carbon, and panty hose (hehe) but I have no idea about the end caps, reducers, and screw clamps. Is this something where I could walk into my hardware store and say, hey I need a reducer, and they'd point me to the right product? It seems like you'd have to have more specifics but I have no idea what these things actually are. Thanks for any help, sorry if this sounds retarded...
