Here's some pictures and info on my 16 gallon uds. After seeing the UDS that Sawzall made, I decided to make my own. I came across a couple of 16 gallon drums from a buddy of mine. I had thought about a small-scale UDS, but didn't know what to do about the racks, lid, etc. But after I saw the post from Sawzall, I proceeded to the local Walmart to find the Uniflame charcoal grill for $22..... lucky me, they were on clearance for $5, so I bought 4 of them. Now as I get more drums from my friend, I will be making more of these babies. They are really simple to operate, and use very little fuel. I think I have $15 into this one. The lid/rack/grate cost $5, the expanded metal was $59 for a 4x8' sheet, so $3.50, a can of tremclad bbq paint was $7. I already had the pipe fittings and valves from a machine I bought years ago for scrap metal. Showing my lack of originality, I even used my candy thermometer through the vent in the lid. à Showing the inside with 2 racks installed. The charcoal basket. I wrapped the 11" grate from the grill with expanded metal and welded it in place. I put 3" legs on it. Some side ribs on the moker. Thanks for looking... any questions, just ask. DanVan.
