I built a Kettle Pizza clone and after doing a lot of research, I thought I'd give a baking steel type lid/deflector a shot.
I had a concrete saw blade and the bottom of the drum I used for the KP clone and bolted them together with a cook grate for handles and as a spacer between them - basically to cut down on the weight.
It worked fine, and if I stayed with the KP clone, I'd still use it. So I suppose I could recommend that kind of setup. It was just too much of a hassle for what I was trying to accomplish.
I'm much happier with my Chop-Top Pizza Kettle.
