I apologize, but I didn't read every post on this thread. I followed the instructions from the post and built myself a MLT for about $90 out the door. I bought all the parts for a second one for my brother as well. I am currently enjoying my first all grain 1.75 IPA (not quite a double IPA), and I'm quite happy with the results. My tip for those who are going to build this: Use an angle grinder with a cut-off wheel to separate the stainless from the fittings/hose, it makes the ends of the SS sheath nice and clean and easy to work with. Also, I used regular zinc cut washers for the inside fitting as I was unable to find SS washers large enough. Big mistake, they were rusting after the first brew. I've done two brews since then, but now the washers are rusted to the point that I can't risk ruining a brew. When I got the parts for my brother's MLT, the home depot had the "Create a bolt" kit in stock, so I'll take some of his (they weren't in stock when I built mine).
Just looked up my receipts, the total cost in the central valley, CA, 2012, was 89.18 out the door.
I put mine together in less than an hour and used it the following morning. This is a perfect example of ignorance being bliss; I was only somewhat familiar with the concepts of AG brewing but I tried it and it worked out. Now I need to learn exactly what it is that I'm supposed to be doing, rather than relying on dumb luck...
