I recently got my hands on two 30 gallon barrels (pictured), one with lining and one without. I also have an old unlined 55 gallon barrel (not pictured) thats been laying around for a while. My plan is to build a basic UDS with one of the 30 gallons, and a "T" style with the other 2 using the 55 gallon as the base and fire chamber and the other 30 gallon as the grill/smoke chamber. My friend will sand blast and powder coat the barrels for me, and then I plan on using high temp paint to coat both the insides and outsides. I have a bunch of questions for the "T" design though... 1) Is it better to do all the cutting and welding before or after I strip and coat the barrels? 2) If I'm painting them after I put them together, do I need to powder coat at all? 3) Are there any other steps I'm forgetting?! I have a design planned as far as grates and intakes and an adjustable heat diffuser. I will also have a plate I can put in the bottom of the top chamber so I can grill regular style as well. Any and all help and guidance is greatly appreciated. This is my first build and it definitely won't be my last. As far as I'm concerned, and I think you all will agree, theres nothing finer than spending a weekend slow cooking meat and drinking beer while sitting around the yard with family and friends.
