Picture the little aluminum disk riveted to the top of a Weber kettle. It
closely matches the profile of the domed kettle top.

I want to make something similar in concept, but with different dimensions.
I find I have no idea how to shape e.g. a 4" soft aluminum circle so it
will lie close to the OD of a rounded 3D surface like a tank end.

This is for making a smoker vent ..

Hey, Grant.
Did you ever get one of the canvas lead shot bags that Boeing Surplus
had years ago? My son and I found them and each got one. He cleaned
and washed his really well and used it to hold fossils while he
cleaned the stone matrix away. I still have mine in original condition
and don't think I have ever used it.
