Heavyweight PVC pipe. About 8" long.
Cap glued and screwed on one end. Drill a hole small enough to fit a butane refill can valve to in that end.
Take an open cap for the other end (threads and lip but no endcap) and epoxy stiff, very fine stainless steel mesh into the end (cut into right sized circle using metal shears). I used 2 layers of mesh.
Fill tube with very (very) dried out ground-up trim, small buds and even inner leaf.
Go outside. Way outside. Like at least 150 feet from any source of flame or spark of any sort. And put some eye protection on, yeah?
If you do this indoors or smoke a joint while doing it or something dumbass like that you're going to likely die in an enormous fire and in tons of pain.
Hold the tube mesh side down about 2 inches above a pyrex baking dish with a paper coffee filter loosely around the mesh end of the tube to stop plant matter from going into the oil.
Put the stem valve from the butane refill can (use highest quality butane like Colibri only) into the hole. Push down to release butane. Dump the whole can of butane through the tube. Wait 30s. Repeat with a second can if you want max yield. Wait 30s.
The pyrex will be filled with liquid butane and weird oils and shit. The butane will boil off quickly at normal outdoor temps. If you want to make it boil off faster you can sit the pyrex on top of a hot water bottle. Don't put it on the stove or something fucking idiotic like that or you will die. Painfully.
Let all the butane boil off.
Once there is no more visible liquid, take the pyrex dish inside. Wait about 30 min.
Using a razor blade, scrape up the layer of oil / wax inside the dish. This will be very, very, very sticky. You'll think there isn't much, but it will start to build up quickly.
Scrape the oil / wax into a small glass container. Let this "cure" at room temp about 24 hours.
Smoke using a skillet or a vapor globe or a hash oil pipe (or a fucking crack pipe if you are desperate).
As a warning... you'll notice that one hit will make you progressively more high over time. For most folks, if you do this extraction well, you'll get more and more high for about 30 min from one hit. So don't do two quick back to back hits until you're used to the specific oil you just made as power can range.
