Gents, I have been scouring the forums for weeks now looking for info, tips, insight, whatever I can find regarding designing my smoker. I figured I might as well post up my specs here and let you guys shoot holes in my design so I can make it bulletproof. For background, my brother-in-law advised me that he has connections through which he can get me sheet steel, and we can weld it up in his garage. So I did the design up from scratch using Feldon's calculator and a bunch of ideas from here and elsewhere on the internet. I want to keep the thing small, as a roll-around backyard unit only. I had it at a 48" cook chamber, but downsized it. I want to use 1/4" steel throughout for heat retention. I want two levels of cooking surface, both slide-out. I designed it as a direct-flow, but I have been toying with making it reverse flow. Jury's still out on that; opinions on doing so in a cooker of this size? Anyway, here's my drawing. It's rough, mainly to show dimensions and to allow me to calculate volume for the Feldon's worksheet. The front view doesn't have a CC door drawn in, it will fit in the opening with a flange around the edges. I'll figure out a firebox door and all that stuff in time. And here's the link to my Feldon's worksheet: http://feldoncentral.com/bbqcalcula...22.01&fi=6,5,0,25.92,0.86&fc=9.38,13.27,69.12 Any critiques or suggestions will be most welcome!
