As some of you may or may not know, I work for an Oil Pipeline Co. and on our current project we are using a .38" (that's just a over 3/8" for you "non engineers") wall thickness 30" diameter steel pipe. I've been talking to the guy in charge of the pipe supply and of course the scrap pipe and he said I could, very possibly get a hold of a decent length (4-5ft.) of scrap pipe for FREE!!! Now my main question is, other than the sheer weight of this particular length of pipe and how I would HAVE to have counter weights for the lid, how do you think it would do for cooking? I know it'll work just fine on warm days but when it's cold, wouldn't it take quite a bit to get the cooking chamber up to temp? I'm planning on doing a trailered Lang "clone", but the weight and thickness of this particular pipe is kind scaring me. But, then again FREE is a damn good price! Let me know what your opinions are on this matter. Thanks!
