Scottie - Love the idea of using a soldier's helmet, very outside of the box.
But I have to ask, does the dome need to be made of metal?
Would fibreglass with some heat reflective material on the inside work?
Not sure if you have read
SeaNick's build thread?

But he would probably be doing something based on a drinks bottle for that shape.
Obviously not great timing with the suggestion given how much work you've already put in.
Good luck, Paul.
