Thanks for the replies everyone.
The lid that I cut was off of a performer that I have completely restored. The performer was in decent shape with lots of paint missing from the frame. The ash catcher was rusted through and all of the paint was missing. The biggest issue was a lid that had been dropped or previously used as a bludgeon and dented so badly around the edge that it wouldn't have been useable. So I ordered new wheels and casters, sanded and painted the frame, sanded and sealed the side table, replaced the ignition and bought a new 22.5 inch kettle to use as a donor replacing the lid and ash catcher and the grill grates on the performer, and repurposing the lid and rest of the remaining brand new kettle to use as the pizza cooker.
The pizza cooker still needs more air. I was thinking of trying to use a blower like might be used in a metal forge.
Let me know what you guys think.
