Nice build, you're going to love using it.
Here's a link to the one I did:
http://www.bbbqs.com/Forum/viewtopic.php?f=43&t=2604I use it all the time, since I'm usually only cooking for two people, I now use it way more than my 22" WSM. It's light & portable and the amount of food it can cook is amazing. It's also very efficient, I can do a 6-8 hour smoke on about 1/4-1/3 bag of charcoal.
@stevenscustomguitars my pot cost US$51 incl. shipping (£34 at 2012 prices) - the total build probably cost about £60ish (Pot £35, extra cooking grate £11, bolts £3, thermometer £5 (ebay), high temp paint £8). I already owned the Smokey Joe and because you don't need to alter it at all I don't count it as a cost as it retains it's original function.
If you can't afford the new 14 inch Smokey Mountain - which I reckon they brought out because most BBQers in the States seem to have built a Mini WSM - then this is a very cost effective way to get a great small smoker.
