The use of lead foil

Well, why then did I built that nonsense above? The answer is that I use it as a form so that I can emboss a shet of lead foil over it -indeed I want the shape to be completely hollow.

So here we go, I first place the lead foil over
lead foil over form

I adjust ii on  one end

lead foil over form one end

And then on the other

lead foil over form the other end

In the end I have this.
it will soon be time to reinforce the inside of it because the slightest touch over it will deform the shape
