Go to Pizza Making equipment, Ovens and go down to 9 Minute Pizza
I could not post links when I did this, so I will leave it as below.
Here are some diy pics. You need 21 or 24 inch Weber grill, I forgot the size,
A 3/8 steel plate that fits inside the Weber just a bit bigger than the stone. My plate is 16x14 and just fits on the long side, so if I did it again, I would probably go with a 15.5 x 14.5 plate. Measure to be more exact. I was lucky and the 16 x 14 works.
1x1 inch cut steel pipes,
No galvanized metals etc.
Low cost 15x14 American Metalcraft stone or tiles or whatever,
Neapolitan dough or your own; stuff,
Cornmeal or semolina for building pie on peel and for stone
You can use upside down cookie sheet if no peel.
I must add this: The fast bake times allow you to pre assemble say four large pies on cornmeal laden cookie sheets, for a sort of dinner party production run.
Use the peel to remove and serve as they go every eight minutes or so. Never could do it this fast in oven, at least mine.
