just do a search for butane extraction method or something. just remember never do it inside or near any spark or flame. instead of copper or pvc I used an empty m+m's plastic container and drilled several small holes in the bottom and 1 small one on the top. the top hole must be big enough for the very tip of a butane nozzle to fit in and small enough to not let the wider part of the nozzle through. the collecting dish is a small pyrex bowl.
the thing about the butane method is that it is very selective of what it pulls out of the plant matter. only the non freezable thc oil. it is called a supercritical fluid extraction.
also remember to evaporate some straight butane first to see if it leaves any residue upon evaporation and if it does do not use it because it most likely contains carcinogenic additives
