what to look for in a vac and chamber setup

not sure about the tube.. im not sure if I would like the glass ones. I love my honey bee extractor. it works great, cheap too and safe (35$): http://www.ebay.com/itm/The-Original...item2322e068fb


and this is my vac set up that I just ordered. the desiccator is bad ass, dont think it gets much better than that for that price range. and I cheaped out on the pump. well see if I regret that in a few months I guess. it costs 250$ to vac purge oil, and thats with a pretty nice set up IMO... im sure you can go much much cheaper like a hand pump and a old jam jar lol... id imagine getting shattered glass shards in your liquid BHO wouldnt be fun though. and im sure you can spend 1000$ if you want, hell even 10,000$ if you want or 50,000$. its ridiculous. just for an extra 5% potency and 1% reduction in butane lol.

desiccator (120$): http://www.ebay.com/itm/190782290423...84.m1497.l2649... if you get this. it makes life easy. an easy life is worth tons of money. this is only 120$.... its VERY easy to apply heat in this desiccator (same as the SS dish from wal mart that I cook the oil off into, you can scrape it, then drip it onto parchment paper, then lay it in that SS desiccator, put that into hot water, pull a vacuum and let it sit. pretty simple I think)

vacuum pump (110$) : http://www.ebay.com/itm/121035768701...84.m1497.l2649

get yourself a stainless steel dish (3$ at walmart) or a pyrex dish (hard to scrape corners... can crack. for 10$ at walmart). pyrex is also hard to cook off because of the weird square shape. the SS dishes work perfect. you can scrape 100% of the oil out, and your butane dish will sit great in another SS dish full of hot water for prime evaporation. while youre at walmart, grap yourself a pair of forceps (7$ in fishing section, get good ones. tough ones) and a 10 pack of straight blades with in the tools isle (6$). grab a case of butane while youre at it, and maybe a few extra lighters, theyre handy to have around for this.

pretty much looks like this when youre scraping, works awesome... then just heat the back of the blade with 1-2 second flashes of the lighter, with 2-3 seconds between, maybe 2 or 3 times and all that oil drips off onto where ever you want it.... onto a piece of glass, tin foil, parchment paper (freezer to get it off), into a vial, or small drops right into the bowl if youre a pro.






20 grams of oil in the dish, then on the paper. I didnt even lose .05 grams in this process. its very efficient. can be very messy though if youre clumsy and fuck up!!! weve all done it.







after spraying. stick this bad boy onto the same sized dish, or larger, full of hot water, outside in the wind if possible, and let er buck!!

i want that desiccator vacpurge, dayumm... im getting over my ghetto rigs..

5% potency increase my ass.. my cheap ass vac and jam jar been giving me pretty amazing potency IMO.. now recycling solvents is a different story..

parts list for oil.wax: (followed by my price)

trim - free
tube - $80
hose clamp - free
coffee filters -$3
5x + refineed butane - $2.70 a can
pyrex - free
parchment paper - $4
controlled heating pad - free
vacuum - $160
desiccator - free
thermometer - $40

total: $290.. adding 2.70 per can of butane

i think thats every single part necessary..

thats the recommended parts for ANYONE really wanting to beef up there oil game..

hand vacuum pumps are shit and worthless, unless you like working out.. any of these 3cfm + pumps should do you fine.. a name brand one might be worth it for the long run..

.. I absolutely loveeeee what my setup produces.. a new desiccator sounds like a worthy investment.. i feel thats where i am lacking.. but then again, im really good at controlling the heat in my mason jars.. not sure how good i could control the heat i na huge pot.. i have a feeling it would be much easier.. but then i have a 3cfm pump, i huge pot take daysss to vac up, hahahaaa

It looks like people are buying the 1/3 hp vacs, from this and other posts. I was looking at the 1/4 hp ones, but I guess you always get what you pay for.

After an initial blasting and purging, how long are you keeping the warmed bho in the chamber under vaccuum pressure for each purge? Is this something you do once for a long period, or do you take it out, reheat it, and do multiple purgings to get it cleaned out of the butane?

from my experience, nothing has ever been the same.. each time i get trim, its from a new supplier, each time i have to make bho, its a new process. there is not one setting.. there aree many multiple vacuum occurrences, along with devac.. I FUCKEN HATE IT SOMETIMES.. BUT, I OVERALL LOVE IT :]

1/3 HP sounds better..
if you start off with a good pump, you probably wont have to upgrade it ever.. also, i really feel a proper desiccator is worth the $ for not having to put up with bs of a home made one.. ive pulled so much oil in a small chamber, bigger = badder i hope to get a new chamber next payday..

material input is a huge factor for your process... from my experience, the fresher, and better the material, the easier the process... old stuff always is a pain in the ass for me..

I have to admit that I'm quite overwhelmed by all the equipment for concentrate making and smoking, so I could really use some advice from the pros here.

First off, is it worth the investment to buy the vac and chamber for making oil/honeycomb? Assuming it is, and taking into account I'm on a budget now (I need to relamp all my lights), can anyone give me a hand picking out some equipment that is affordable and what the job requires.

I don't know anything about these things, and don't want to buy the wrong stuff. This is for me and several people I grow mmj for, one of whom has cancer and really loves this kind of stuff.

I'm trying to search though here to find info on questions like after blasting, do I need to heat the oil before it goes into the chamber each time, how thin do you spread it out on the parchment paper, this kind of stuff. There is so much chatter in these threads its hard to pull info sometimes. Any advice is super appreaciated.

thanks!

You will need both vacuum and heat for what you propose. We use a glass labratory dessicator with a Corning Scholar 170 hotplate inside, but you can do the same thing with a stainless steel vacuum pot used for degassing epoxy castings, which you can set on a hot plate.

I would suggest making your own from a pressure cooker or heavy crock pot, and just make a acrylic lid for it, so you can watch. Tap plastics can supply the acrylic sheet and Paramount Supply, or Gasket Specialties can make a custom gasket for you if you don't wish to cut one yourself from sheet.

We use both a single stage CPS VP6S 6.2 cfm vacuum pump and a Robinair 15500 5 cfm two stage vacuum pump, typically used for air conditioning evacuation. Both have worked well for the purpose, but everyone seems to grab the 6.2 cfm pump first, because it pulls low enough to get the job done and is faster than the smaller two stage.

You will need a full port isolation valve between the pump and chamber and a second bleed valve to atmosphere will speed backfilling up once you are finished purging.

You also need a vacuum gauge capable of -30" Hg (-29.92"), preferably in 1" increments. Because we have them we use compound gauges, which show both pressure and vacuum, but they are not required for this application. We like Ashcroft gauges http://www.ashcroft-usa.com/?gclid=C...FWlxQgod1jEAfw, as well as the ones we get from RSD refrigeration supply house, which have finer graduations.

spot on.. you can explain things very well fadedawg
