I've built some good processors and wash tanks by using a closed-head drum turned bungs-side-down, and screwing all kinds of fittings into the threads of the bungs (the other side of the drum, what used to be the bottom,can be cut open completely, partially, or just punctured for plumbing fittings... also open-head drum lids (gasketed drum lids) can fit into the opened up end of a closed head drum, so that without brazing a thing, you can have fittings on the bottom of the tank and in the lid of the same (some open head drums have two bungs in the lids, and most have no bungs, but it's really easy to thread something into there and make it work, if you have access to hole saws and the like).
(AAAAAAAAAAARGGGH now I really gotta get off my lazy butt and take pictures of this stuff and the methoxide mixers for journeytoforever, they'been asking me to post them for months!!!!!!!!!). There's some photos of one of the designs on the veggieavenger.com website, in the photos of the class I taught in October. (it's in the events section of the website or something). In the photos of us making a tank with pipes inside of it, the design is for a wash tank- you can't get a completely clean separation in a flat-bottom tank, but you can accomplish a lot with flat-bottom drums if you can pull fuel from a higher point than the total bottom. My friend Sean Parks came up with this one. We went around calling it the Sean-style settling tank for a while but it got cumbersome- I've renamed it a Dual-Outlet Settling Tank (one internal pipe picks up fuel from a point higher than the other outlet). Otherwise if you want to add fittings to a drum, braze them. It';s easier to braze to the flat side than the curved side. Mechanical fittings (ie stuff that screws together into a hole, and seals with a gasket) are available but not all that great for biodiesel- the stuff finds a way to leak through just about anything. mark a wash tank (leaving the settled out gunk at the bottom). Does anyoned have a good technique or know of suppliers for the necessary parts?
