I Just finished my first offset smoker build, and thought I'd share some pics. Body made from 1/4" pipe and plate, 3mm box section for the stand, and cast iron wheels off from amazon. Link was on this site

Was putting it together for a significant birthday party (my own), and of course didn't start early enough, so it ended up a complete rush job at the end. I tigged the whole thing out, which took me absolutely ages - I really ought to learn to stick weld!
Still have a snagging list to work through now the time pressure is off, but am pretty happy with the end results of the build and the smoking seemed to be a big success (beginners luck I'm sure).
