It's been a long time since I've been on here. I built my first UDS probably seven years ago from instructions I found on here. I was on here pretty regular until my wife got sick with crohn's disease and her care took up a lot of our time. Glad to say she is now in remission, 7 years and 30 operations later . Anyway... She is my right hand when it comes to prepping all of this stuff for "Q" ing. I'm in the process building a new back porch and outdoor BBQ station complete with a brick offset vertical smoker and a bar. I am in the process of drawing my plans right now...There is not a lot of help on the internet with a project like this, I found a couple with some pictures, and I use feldons pit calculator to calculate the opening between the firebox and smoke chamber. Keeping my fingers crossed... I have a brick mason who's going to give me an estimate soon
