That's really far far too complicated. Just get some old leaf springs, set up a fire and start hammering.
If that's not good enough, then I suggest a careful extraction of iron from that skyscraper size doobie you are hiding. That weed has iron, see. All plants do. When they lose iron, they turn yellow. There's your iron. All you need.
Now stop trying to change the subject. I know it's hard.
No, no it's not too far off topic, there is no "shut it down" now.
The Moon is a small, close light projected off of a mirrored steel alloy dome. You wanted to know the source of the iron in the dome and it's blood.
You reject this and say iron comes from the hot fusion inside stars that are suns that are heavy balls millions & billions of miles wide, and billions & trillions of miles distant, and these massive thermonuclear bombs that never stop exploding are held aloft by a theoretical force (relativistic gravity) that can't be proven and in fact has been falsified (Sagnac-D&P 1939). This magic force that has been experimentally falsified at the University of France in 1939, you claim also powers an un-provable physical chain reaction (hot fusion; "just give us another $10 billion dollars and 10 more years") that produces the iron that somehow makes its way to our Earth that you claim is a sphere with a pressurized atmosphere on its surface that's spinning in a vacuum.
Unfortunately (for your rebuttal) stars, much like the Moon are close, small projected lights and the iron that's in our blood, that comes from the plants we eat, doesn't come from lights in the sky. It's ultimately produced by a process called... can you guess?
When you look at all nature around you, you see that God doesn't make things like mirrors that hang in the sky with projectors that project images or light onto those mirrors, to be reflected off them. Certainly God makes light which reflects off things. But He doesn't make the kind you are talking about. So, who made them and how do you know?
