Okay, I was given an 18 inch performer with a broken shelf / tray. I removed the broken tray, welded some flat bar to the tubular frame and mounted some wood to make a custom shelf.
I also made the lid cut mod as it was a freebie and fixed the grill to the lid to raise the height of the pizza stone.
I used a chimney of charcoal to get things going and added firewood from my log store to raise the temperature. I think I put my homemade dough and sauce pizza on too soon as it was way too smokey. We ate a good portion though.
As a first time experiment, it worked. The dough rose, the bottom cooked and the crust charred. Next time, wait longer for the smoke to die down and a less thin sauce.
The point is, it worked!!! The principle is there, it just needs tuning. As a project, I loved making it, especially as I'm a novice to welding too.
