Hey guys, I am building a couple smokers out of JD whiskey barrels (wood). I have them just about complete but i am having trouble coming up with a charcoal tray, water tray and ash tray. I have about 20" diameter at the bottom of the barrel to work with and maybe a total of 7"-10" tall. Anyone have any good ideas? I need to keep them on the cheep. And do I really need a water tray? Thanks
