what is the lining they use in the barrels? How do I tell if the barrel is lined, or not? I am assuming if I am seeing clean metal, it is not lined??
I'm guessing paint liners are either epoxy or enamel based. The color is usually a brownish tan. I suppose tanks could be lined with clear poly.
Here's a test. Spray the inside of a clear drum with a little water. A day later, you should see rust if it's unlined.
I would bet that is a galvanized pan. If it is I would ditch it. Most of the lids you see are from "open head drums".I made my first UDS last weekend and smoked up a 12pd turkey with no problems at all. The issue I had was the lid. I see everyones pictures here and wonder how they were able to save the lid from the barrel. Where exactly are you cutting the barrel to keep the original top of the barrel as a lid?
I used an aluminum tray used to go under hot water-heaters and put Garage door weatherstripping around the inside. It fits snug and well, but I will be building another for my Father, and would like to keep the lid.
When it says “rust inhibitor” does that wash off or do you need to burn it off?
I believe the norm is to have 1 valve and three additional air intake nipples.
One valve is all that is needed. If you go full open and don't get temp,remove cap and throttle back on valve. With 3/4" nipples I find at most I ever needed was 1 cap off 1/2 throttle valve. i put 3 nipples when making it , 1 for reserve.
