Didn't see any posts here about BHO so I figured I'd post up my step-by-step for the method I have migrated to over years over experimentation and hundreds of runs... :headbang: UNFORTUNATELY, I am having a difficult time finding the pics that go along with this post as the original server I had them hosted on (an old website of mine) is no longer operational. I will find them and upload them as soon as I can. In the mean time, I think the post is pretty specific and should get some people an idea of how one can make top shelf BHO on their own back porch. Without further adieu...
1.) Prepare material (if using bud, trim all stem and leaf matter - this is only because of the quality thing I mentioned, most people probably won't notice a difference if they leave some sugar trim and stem in there)
2.) Prepare extraction tube/oil dish/hot water tray. This is probably the part that I consider the most important so I'll go into a bit more detail-
a.) The tube should be packed firmly but most importantly EVENLY. Contrary to popular belief, it is NOT typically tubes that are packed too full that "blow out" but tubes that are not packed evenly. and if you've ever had a blow out, you know it sucks ass and you damned sure don't want it to happen twice
I used to use two coffee filters (#6 natural IIRC, maybe #4 it's been a while) as well as a metal screen with a collar clamp...eventually once you learn how to properly pack your extraction tube(s) you can step it up to only using one layer of coffee filter and no screen, this is ideal.
b.) I prefer the deeper square pyrex dishes for ease of scraping, but I'm not very OCD about the corners that inevitably stick and can't be scraped (not particularly important, just a footnote)
c.) I use water that is just below boiling, around 190-200 degrees (F) - I don't have anything other than years of anecdotal evidence to support this, but I find that BHO purged with water just below boiling is always overall better quality in the end than BHO purged over a pot of water at a rolling boil (not to mention it's much safer NOT to extract over an open heat source, even if it's outdoors on say an electric burner...)
3.) Run the BHO through (as I mentioned before, usually 1 can or less per ounce of material) - and as you've figured out now, I toss it out after that first run
4.) Time to purge, this is a two step process -
a.) First is the hot water evaporation, wherein I simply put the tray over the hot but not boiling water and allow the extremely volatile butane to "boil" out
b.) After the oil stops bubbling, I use the standard flame purging method - PLEASE to anybody who isn't experienced with making oil, take extreme caution in making sure that you have evaporated the majority of the butane before doing the final purge...I've had more than a few 4 foot tall blue flaming torches over the years from doing this without proper lighting or in a rush. This is NOT something to fuck around with and do in your spare time without proper knowledge, you absolutely CAN seriously injure or kill yourself or somebody else if you fuck this process up.
5.) i typically give each run about 20-30 minutes to "air cure", then I put it right back on the hot water for a few moments just until it's almost too hot to sit the tray on your lap
6.) Scrape and enjoy.
Like I said, I will try to get those pics up ASAP as soon as I find them. In the mean time, here is a pic of the finished product:

I realize I have left some pretty important info out for anyone who is just now finding out about BHO, so please do not hesitate to ask questions about something you don't understand! There is so much more to be said here about this subject for sure...
thx for looking guys, hope I can convert some of you dry sift/bubbleheads to oil! :dance2:
