Thanks guys - this gal is truly tickled with her work... (with the help of hubby and a friend.)
The friend who cut the top out took the liberty of adding/welding on a thin band of metal around the edge - as he says 'to keep the lid from sliding all over the place.'
It's a nice touch, and I'll be adding a bead of high-temp silicone to give it a better seal. I'll have more pics tomorrow.
