Which will get you warm rust.

Iron is basically useless for anything other than frying pans and
decorative fences; you need steel.

Read what it takes to make steel:

And that just gets you the raw stock, not finished goods.

You don't seem to understand what it takes to turn dirt into a nut and bolt.

Yeah, the asteroids are just full of things like screws, insulated wire,
and sheet metal, not to mention plastic.

Nope, to make a motor you have to have all sorts of other things like
wire, metal stock, insulation, etc. You have to have all the stuff
found in a good hardware and industrial supply store.

Be aware that it is not me that did all the silly crossposting.
