#1 - You must be able to create a full vacuum for a few moments at the very, very least. I know people make use of some pretty inexpensive methods to extract/purge. But, to do it correctly, if you don't want to spend 4 hrs. on a 6 gram return, and you want a good product, get a good vacuum chamber (not the one you have), and a good vacuum. The easiest part of the whole process is making a vacuum if you have the right eqpt. - then you can start to create your own personal style of production. Cheap eqpt. makes crappy products.
BTW - for all the econo-growers, I know you can only use a milk carton and a 90w light bulb and get huge returns, (sarcasm), so this is for everyone else...
PS - get rid of the hand brake. And, don't buy a converted chili pot off Ebay for a vacuum chamber. If the chamber cannot handle whatever vacuum you extend, or if you introduce heat also, that thing will crumple, and the top will blow off whatever is above it. I think we don't see this on Youtube too often except for news clips, because it's a serious f-up. I'd love to see what it looks like, but the closest video I saw was a guy who blew off part of his hand - the police found parts of his hand on the ceiling/floor/wall of his garage, and of course, a good amt. of blood. I don't know what happened though, the news people only mentioned that he was making BHO, but their details were a little off...(he could have been using a tank of gas at a time..?)
BTW - Absolutely last thing, don't extract BHO method through a tube without creating a reaction so the most volatile amt of butane is released.
I saw a video on Youtube where a guy thought it was a great idea to extract about 5-6 pipes of extracted material b4 starting the reaction.
I wonder if he is still walking/breathing. Bad idea to keep that gas (which sinks and stays down without strong ventilation) sitting around just waiting to react (when you're not ready...).
Best of luck though. BHO is cool if done right, and safely.
