When I first started toking, I would spend a good hour sometimes looking through pipe fittings and such at the local hardware store. I'd make all kinds of pipes out of fittings. They were all metal mind you, but a glass pipe was unheard of then.

Now I don't bother making pipes anymore. I just buy them now.

My main piece is a a bong, when I'm at home. When I go out or something, I use a glass spoon pipe. I arely roll joints though, only if there is more than 2 of us, then I'll spin one up as it's better than packing bowl after bowl.
