I decided to build a UDS after reading all of the praise about these beasts. Here are some pictures during my build. Here is the beginning of my build. I used that shoe string to measure the exact diameter, and to mark where i wanted my two inlet valves, and main valve to be. I then used those markings to keep in line my markings for the grate holes. i have a two grate system, but have three different levels to choose from. One three inches from the top then two more levels six inches down at each level. Here i installed everything just to see if i liked where everything was lining up. Yes that is the red liner of death.... I burnt the thing out three times, and I am grinding it here. My neighbors probably thought I was an idiot when i started grinding the inside. Word of advice, AVOID THE RED LINER AT ALL COSTS. It sucks a lot.... Here I am preparing for paint. I used a high heat primer, and high heat black and grey paints... Here she is all together, and being seasoned. Cant wait to start cooking... One more for the road..
