Well, these forums are a bit slow at times, so I gave something a try. Every BHO tek/tutorial I've read mentions filling the tube it all the way, so I wasn't comfortable running the butane through a half-filled tube. I used aluminum screen on the end for a filter (plus a "disk" of coffee filter) since it doesn't corrode. What I did was cut up some strips of screen, folded them up accordion style, and filled the gap. I figured it wouldn't react with the butane, so why not?

The pan is outside in its bath now, and everything looks as it should...have some nice bubbles in there. I should mention that this is my first attempt at BHO. Used a stainless steel turkey baster and 2 small cans of Colibri.

In addition, I'm considering doing an ISO quick wash with the plant matter matter remains when it dries. Anyone think it's worth it? Bad idea?
