Revisiting helmets and billies

I know that we had this discussion before, but since then there have been a lot more new members on the forum, and maybe someone else has something to add about this.

Has anyone come across a metal helmet that you can cook in, yet? (like the WW1 ones). Or, an aluminium bowl that is the right size to beat up to fit around a head. I tried a large Sigg billy, but it wasn’t big enough (billy too small, not head too big!).

Anyone tried welding aluminium??
