If you missed it, I am itching to build me one of those UDS's. I have been searching high and low for a 55 gallon barrel, but I have not found one that my wife would approve of. She is over concerned about what was in the barrel. I have access to unlimited closed top barrels that are pristine for $15. They stored mineral oil, so I assume that would be safe to use. The drawback is that I don't have the tools to cut the top. I can see future injuries on the jagged edges once it is cut too. Then I would have to buy a lid, (Weber top), so it seems like to pricey of an option. I can buy a brand new barrel that is open topped with no liner for $113.00, but that sort of defeats the purpose, as I can most likely buy a cheapo smoker at Walmart for less than the drum alone. The $113 barrel is a heavy duty barrel with more weight. (thicker metal) I have already spent $20 on gas on two unsuccessful craigslist hunts. People were less than honest on the condition of the barrels. I can get recondition barrels on ebay shipped for $43, but they are lined. We have a no burn policy in effect right now, so I will not be able to burn the paint out until the winter rains arrive. Way too late for me! I guess I will be patient.......thanks for listening.
