You’re looking at the bottom of a round bottom flask as seen here:

So I started with the Yama, but thought it would be a fun project to try to make something from scratch. Had to turn to chem glassware, which is a little pricey but I think looks cool. I used a separatory funnel, Buchner funnel, and Florence flask.

Glassware ended up costing about $83, and I used the ring stand we had in the science lab at school.

Round-bottom boiling flask, 5000 mL? In all seriousness, these puppies aren't exactly $5000 watches, but they do go for an unexpectedly pretty penny.

Try:

  1. dealextreme.com / dx.com (same place) or focalprice.com for infrared thermometers (their prices include shipping, and yeah, when you look up iphone cases, you'll be upset if you've ever bought one in NA at a mall stand) - the dealextreme.com place has a ton of electronics stuff, arduino-esque stuff too if you're wanting to get fancy

  2. food-grade vinyl tubing at plastics/marine/hardware store; there are different types so ask until you're comfy with what you pick; if you ask at your local head shop, about the glass ends available for this sorta thing, there are several. For my Arizer (something like that), there are a bunch of glass fittings (compatible with other glass fittings I've seen) -wait, here's a link http://arizer.com/store/8-extreme-vaporizer-parts (I just picked up a $20 kit at my local shop with the whip, glass mouthpiece, Elbow to connect to the cyclone bowl, um...the screens for same...and another glass stirring tool... I believe that the 'connections' of the cyclone bowl, and so on are standard scientific-type connections; if you check out science-supply sources, you can find a range of glass 'bowls' you can use that connect to them; if you're in the US, you can even get them shipped to you cheaply...the nice thing, they're certified to not react, to deal with heat to a certain temperature, etc. and aren't going to melt/gas plastics, etc., when you're using them. This may allow you to heat directly on the glass itself (just drop to the bottom?) - think 'lightbulb vape' but not likely to kill you....

    here's an example - http://www.amazon.com/Chemglass-CG-1512-09-1000mL-Single-Evaporating/dp/B005WVRHFS/ref=sr_1_82?s=industrial&ie=UTF8&qid=1348542044&sr=1-82

    For that, it takes a standard glass connector (I think similar to that found in the Arizer packages) - but you should be able to get one with two holes, if you want (or a 2 way connector than plugs into the top to allow airflow etc. (you could actually put this on top of a cheap hotplate to get it going (scientific ones are $150+, but hell, you just need evenly distributed heat). If you really want to get fancy - check out these: http://www.amazon.com/s/ref=nb_sb_noss?url=node%3D318083011&field-keywords=20%2F40+joint&rh=n%3A16310091%2Cn%3A%2116310161%2Cn%3A317970011%2Cn%3A318049011%2Cn%3A318083011%2Ck%3A20%2F40+joint

    Anyway, I've not followed through with my plans, but that's some of the stuff I found when I researched it a couple years back.

    edit: oh there are also mason jars, of course, which tend to put up with heat fairly well. I did a quick test the other day, just punching two holes in the metal lid, and tossing some pot at the bottom of the jar - I held the base (with the pot) over the edge of my gas stove's flame, and presto, vapor ... I'd do some checking to see how much heat/the limitations for this stuff.

    edit2: if you're really temperature picky, invest in a calibrated hotplate - then you'll know exactly what you dial in is what you'll get. Hmm...now I'm wondering if something like this: http://www.amazon.com/1800-Watt-Portable-Induction-Countertop-8100MC/dp/B0045QEPYM , with a mason jar sitting on an old cast-iron pan (or does it need to be steel?) may just work...the conductive stovetop heats the pan, which heats the glass (this is where a flat bottomed boilign flask would be best, since the heating would be even), which heats the pot, which you then enjoy :D

    edit3: Depending on your 'container/bowl', would a simple flatiron (be it for clothes, hair, or craft (the tiny ~1inch square ones)) be sufficient to heat things up? (without all the noise of a heat gun?) ; you can also look into mesh/fibrous materials that you could heat that don't actually come into contact with your pot - (grab some inexpensive copper wire, roll into small ball with air spaces galore that fits at bottom of your cyclone bowl, attach the ends to a 9v battery and presto - a heat source, not in contact with your pot, that you can suck heated air through (that get's heated) to vape? And yeah, I'm at 7 after experimenting with the bong I just made out of a container for 2kg of Whey protein powder, some spare tubing, and a metal bowl/shaft I had lying around unused. HEll, there's enough room there for a bag of ice, and space to spare, I dont' think I'll use my 'real' bong ever again - this capacity was perfect, and it's so easily cleaned. Tomrorow I'll have to get some silicone to create better seals...thanks for prompting my creative energies tonight.

A glass funnel like this to hold the paper

http://www.amazon.com/Funnel-Short-stem-Glass-100/dp/B0017U6H36/ref=sr_1_5?ie=UTF8&qid=1394639219&sr=8-5&keywords=glass+funnel

plus a vacuum flask

http://www.amazon.com/American-Educational-Clear-Borosilicate-Filtering/dp/B005QDPKU6/ref=sr_1_4?ie=UTF8&qid=1394639307&sr=8-4&keywords=vacuum+flask

or a 2-Neck flask

http://www.amazon.com/Chemglass-CG-1520-14-1000mL-Boiling-Standard/dp/B005WX3K02/ref=sr_1_1?ie=UTF8&qid=1394639522&sr=8-1&keywords=2-neck+flask

to hold the coffee and let the displaced air escape. It wouldn't work as nicely as a chemex but if you like the look of labware in your kitchen go for it.

Note: I didn't take the time to find the right size funnel and you would want a bored rubber/cork stopper to put on the funnel.

u/TwitchingRock · 2 pointsr/StonerEngineering

Well its pretty simple, finding the materials is the difficult part.

First off you would want a diamond drill bit, 18 mm is what i used: http://www.ebay.com/itm/1pc-Diamond-Tile-Glass-Hole-Saw-Drill-Bits-18MM-/170891329634?pt=LH_DefaultDomain_0&hash=item27c9eac062

Secondly You would need a scientific boiling flask, usually expensive, but i found nice prices on amazon! This is what i would use now if i knew about the length of the neck previously: http://www.amazon.com/213L15-Karter-Scientific-Florence-Boiling/dp/B006VYY49C/ref=pd_sbs_indust_2

Thirdly Downstems are a must! http://www.ebay.com/itm/200960416812?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

And the grommet(black rubber thing between down stem and boiling flask)you should be able to find one that fits your hole size at a local hardware store such as osh, lowes, or home depot.

The rest of the stuff such as bowl or ash catchers you might want to check on ebay or a local head shop for prices :)

My brother made it for me, I’ll have to ask him to be sure but I’m pretty sure amazon.

EDIT: yup, amazon. https://www.amazon.com/dp/B07X2LWXG4?ref=ppx_pop_mob_ap_share

I already ordered a pipe for 6 bucks off ebay. The last time I ordered off DH gate I got good cheap pipes they were tiny, like an inch or two long but they worked good. Sometimes they got hot and burmt yoi though. The ebay one should be 6 inch and is coming domestically.

Amazon wouldnt let me cancel the order for the fucking round bottom flask though so Im fucking stuck with it.

This is what I got.
