For ease of cleanup I have wrapped my water pan in foil as well as purchased a larger clay saucer wrapped in foil placed in the water pan. In addition to that I take a large foil party tray and bend it a little to fit in the WSM sitting on top of the water pan and this catches almost all drippings form the top grate. Down side is I lose the lower cooking grate. I could place it on the foil tray I suppose but right now I'm focusing on another mod that will get me another cooking surface. I went to HD and got a second 22.5" cooking grate with handles. MY goal is to find or make some kind of spacer that I can put the additional grill on and have about 3 to 4 inches of space between the two upper grates. This way I can do 4 full racks of spares in the upper cooking chamber. Any ideas for the spacers? I'll probably just mull around the hardware stores until I find the right piece unless someone here has a suggestion. Thanks!
