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.
Not really

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:
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.
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.

Lol!
That one was just a joke.
I bought this really long link right here
