OK. Crazy/stupid question here, on the same-ish topic... though I'm doing a butane (Power 5x) extraction. I've watched some videos on Youtube! and see guys using PVC tube. So after my bud tender offers me a sweet deal on $10g Top Shelf shake for $5g, if I do some BHO... I ended up with about 12g of damn good shake and small buds. I did some reading and I see... DON'T USE PVC. Only guy that says, its OK... says not to use it for more than one extraction. @#$% that. I read about some guys using glass turkey basters. I could buy one... but, don't have one. Then... browsing links, I see a simple statement... "I found the perfect downstem to use!" So this gets me thinking. I've got a few nick-knack glass pieces to throw together something, already had an idea brewing. So I come up with this, GlassBlowersDirect 18/18 DS (like 6"), and oregronglassblower 18/14 reducer and old style 14mm whip adapter. Found a fitting on the butane cap that fits airtight in the hole of the adapter. So this is it. Don't laugh yet... Besides... before I burned through the whole 12g, I want to make sure I know what I'm doing. First run, which I'm going to have to clean-up (didn't cover it in time... just a few hairs)... but I did get a nice bright ring around 1/2 the pan and a small puddle. We'll see. I only pushed just over a gram through. But, an update with the pictures. This is what I configured. For size comparison. A big can of Power 5x... 5.8oz/300ml. Also shows with 2 coffee filters attached. Now this is packed in there... but I could probably cram more, if I wanted too. I packed it a bit as I loaded and was able to fit 2g in the DS, up to the 18/14 reducer. Finally, the exploded view. Now dabs are OK. I bought a 2nd purchase, .5g of some more blonde stuff. Its, "eh...". Hits little harder than most of my herb, not all. Karma Bitch still hit like a brick. First stuff I had, was 1 dab and I was medicated for a good 2-3 hours... trailing off slowly after that. This ran thru REAL fast. Too fast, actually... which is why I tried to pack more in there. But this little thing ripped thru half the can, before I really knew what happened. Still, its cheap enough and I've still got 11g to use. Also, I do not want to use heat for the purge. Butane and heat... no thanks. I can cover it and let it sit, I'm patient enough for that. But, what kind of return should I expect on 10g. I'm reading anywhere from less than a gram (Which is a wasted investment), to a couple/three grams. Input on any of it, please... and pardon my ignorance on the subject.
