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.

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 :)
