Here's my set up. I already had the grill and the alum disc is what was left over from the tamale pot when cut for the mini WSM. The lid works just as well.
I must say those are some mighty fine looking D.O. tables. I found an old aluminum highway sign that I use. I set it up on rocks, sticks of firewood or what ever is handy at the time. For me it works very well.
